SUMMARY:Behavioral\, Econometrics and Theory Seminar Series Presents: Kevin Chen
DESCRIPTION:Economics Behavioral\, Econometrics\, & Theory Seminar\nDate: Thursday\, October 23\, 2025\nTime: 1:40-3:00 p.m.\nLocation: Engineering 2\, Rm 499\n\n \n\nSpeaker: Kevin Chen \nTitle:  Assistant Professor of Economics \nAffiliation: Stanford University\nHost: Michael Leung\n \nSeminar title: Compound Selection Decisions: An Almost SURE Approach \n \nABSTRACT:  This paper proposes methods for producing compound selection decisions in a Gaussian sequence model. Given unknown\, fixed parameters µ_{1:n} and known σ_{1:n} with observations Yᵢ ∼ 𝒩(μᵢ\, σᵢ²)\, the aim is to select a subset of units S to maximize utility Σ_{i∈S}(μᵢ − Kᵢ) for known costs Kᵢ. Inspired by Stein’s unbiased risk estimate (SURE)\, we introduce an almost unbiased estimator\, ASSURE\, for the expected utility of a proposed decision rule. ASSURE allows a user to choose a welfare-maximizing rule from a pre-specified class by optimizing the estimated welfare\, thereby producing selection decisions that borrow strength across noisy estimates. We show that ASSURE yields decision rules that are asymptotically no worse than the optimal but infeasible rule in the pre-specified class. We apply ASSURE to p-value decision procedures in A/B testing\, selecting Census tracts for economic opportunity\, and identifying discriminating firms.

SUMMARY:Macroeconomics & International Finance Seminar Series Presents: Zhiguo He
DESCRIPTION:Macroeconomics and International Finance Seminar\nDate: Tuesday\, October 28\, 2025\nTime: 1:40-3:00 p.m.\nLocation: E2-499\n\n \n\nSpeaker: Zhiguo He\nTitle: James Irvin Miller Professor of Finance\nAffiliation: Stanford University \nHost: Michael Leung \n \nSeminar title: Household Migration and Collateral Constraint: Cash-based Housing Resettlement in China\n \nABSTRACT:   Collateral constraints reduce household migration to expensive locations by restricting financing for home purchases. This endogenous location choice can amplify the impact of relaxing borrowing constraints. Using China’s cash-based shantytown renovation program (2015-2018) as a natural experiment\, we provide evidence that cash resettlement– by converting illiquid shanty houses into cash– facilitated household location upgrading and raised house prices in more expensive locations. A dynamic spatial model with collateral constraints confirms that endogenous location upgrading amplified the effect of cash transfer\, raising lifetime housing expenditures by nearly 50%\, and house price growth in low-tier cities by 9% in 2016-2020.

SUMMARY:BME 280B Seminar: Preconfigured neuronal firing sequences in human brain organoids
DESCRIPTION:Presenter: Tjitse (TJ) van der Molen\, Ph.D. (Postdoc\, Sharf Lab\, UC Santa Cruz and PhD Kosik Lab\, UC Santa Barbara) \nDescription: Neuronal firing sequences are thought to be the building blocks of information and broadcasting within the brain. Yet\, it remains unclear when these sequences emerge during neurodevelopment. Here we demonstrate that structured firing sequences appear in spontaneous activity of human and murine brain organoids\, both unguided and forebrain identity directed\, as well as ex vivo neonatal murine cortical slices. We observed temporally rigid and flexible firing patterns in human and murine brain organoids and early postnatal murine somatosensory cortex\, but not in dissociated primary cortical cultures. These results suggest that temporal sequences do not arise in an experience-dependent manner\, but are rather constrained by a preconfigured architecture established during neurodevelopment. By demonstrating the developmental recapitulation of neural firing patterns\, these findings highlight the potential of brain organoids as a model for neuronal circuit assembly. \nBio: Tjitse van der Molen studies spontaneous and evoked neural circuit activity in human and mouse stem cell derived brain organoids using dense multi electrode arrays. His main goal is to gain a better understanding of how healthy neural circuits process information and how possible malfunctions in neural circuit activity may result in disease\, in order to develop appropriate treatments. Tjitse recently completed his PhD in the Kosik lab at UC Santa Barbara and is now continuing his research as a postdoc in the Sharf lab at UC Santa Cruz. \nIn this talk\, Tjitse will present his latest manuscript that is currently in press with Nature Neuroscience\, focused on spontaneously occurring repeated sequential firing patterns that are present in the intrinsic activity of both brain organoids and neonatal mouse brain slices but not in 2D primary cultures. Similar sequential firing patterns have recently been shown to be important for information encoding and learning in the human cortex. The presence of these sequential firing patterns in the spontaneous activity of brain organoids that have never received external stimuli supports the notion that they develop in an experience-independent manner. \nHosted by: Professor Josh Stuart\, BME Department \nZoom Link: https://ucsc.zoom.us/j/99970819390?pwd=8sl5pd5TTBA5f6nqyCzo5mFpaqcEJG.1 \nFull Schedule: https://docs.google.com/document/d/1xD09vITwd_Pj9Ge6hHEuBFa5zBUYu2O-bjpSibt7VHE/edit?tab=t.0 \nRoom: PSB-240

SUMMARY:Applied Microeconomics and Trade Seminar Series presents: Shanjun Li
DESCRIPTION:Applied Microeconomics and Trade Seminar\nDate: Thursday\, October 30th\, 2025\nTime: 1:40-3:00 p.m.\nLocation: E2-499\n\n \n\nSpeaker: Shanjun Li\nPersonal Webpage \nTitle: Steven and Roberta Denning Professor of Global Sustainability \nAffiliation: Stanford University \nHost: Peter Christensen \n \nSeminar title: Range Anxiety\n \nABSTRACT:   Range anxiety\, the fear of depleting battery before reaching a charging station\, is often cited as a major barrier to electric vehicle (EV) adoption\, yet there has been limited formal economic analysis to quantify its importance and understand the policy implications. We develop a continuous-time dynamic model of EV usage and charging decisions to quantify range anxiety as the utility loss from feasible yet unrealized trips due to perceived range constraints. Using high-frequency data of 188\,000 EV trips and 30\,000 charging events among 8\,000 EVs in Shanghai\, we recover model parameters governing consumer driving and charging decisions. The estimates imply that\, across EV models with varying driving ranges\, average range anxiety was about $1\,900 in 2021 but declined to $1\,200 in 2024\, driven by improvements in charging infrastructure and\, especially\, in creases in driving range. Policy simulations underscore the importance of coordinating investments in battery capacity and charging infrastructure to address range anxiety: relative to socially optimal levels\, Shanghai’s EV market has under-invested in driving range while over-investing in charging infrastructure.

SUMMARY:BME 280B Seminar: Anne Nakamoto\, Alan Zhang\, Shelbi Russell
DESCRIPTION:Presenter 1: Anne Nakamoto\, BME PhD Candidate\, Corbett-Detig Lab\, UC Santa Cruz \nTalk: Investigating deleterious mutation burden across populations and landscapes in the California Conservation Genomics Project \nDescription: Biodiversity is being lost at an accelerated rate due in part to anthropogenic forces\, posing a threat to the sustainability of Earth’s ecosystems as well as to human health. A major goal of conservation genomics is to use genomic data to understand population health\, which can inform management decisions for the preservation of biodiversity. The California Conservation Genomics Project (CCGP) is an extensive dataset containing species of conservation interest sampled across California\, allowing a landscape genomics approach to conservation. Among the many metrics that can be used to assess population health is genetic load\, which refers to the reduction in fitness imposed by deleterious mutations. In this work\, we construct a bioinformatic analysis framework to identify deleterious genomic variants in CCGP species based on evolutionary constraint. This allows us to investigate patterns in genetic burden across populations and the landscape of California. \nPresenter 2: Alan Zhang\, BME PhD Candidate\, Corbett-Detig Lab\, UC Santa Cruz \nTalk: Scalable Strain-Level Metagenomic Deconvolution and Assembly Using Pangenome Mutation-Annotated Networks \nDescription: Strain-level deconvolution of metagenomic samples is essential for pathogen surveillance\, mixed infection diagnosis\, and evolutionary genomics\, yet remains computationally challenging as genomic databases expand. Existing methods scale poorly with database size or rely exclusively on single nucleotide polymorphism (SNP) information. SNP-based approaches rely on mutation-annotated trees and thus require well-established reference genomes\, limiting their applicability to divergent species that lack alignable root references. We present panMAMA (panMAN Metagenomic Assignment and Metagenomic Assembly)\, a method that leverages the pangenome Mutation-Annotated Network (panMAN) data structure to enable accurate strain-level quantification across both closely related and divergent genomes. By employing k-min-mer-based pseudo-chaining with a seed-annotated tree index\, panMAMA achieves substantial computational speedup compared to existing k-mer-based tools while maintaining high accuracy. We demonstrate that panMAMA accurately deconvolves both closely related SARS-CoV-2 genomes and divergent HIV and respiratory syncytial virus (RSV) genomes\, outperforming existing tools including Freyja on simulated wastewater samples. Through a hybrid heuristic and maximum likelihood approach for read assignment and consensus calling\, panMAMA effectively recovers variant genomes from low-heterogeneity samples of divergent species. These results establish panMAMA as a scalable and accurate platform that extends strain-level metagenomic analysis to previously intractable highly divergent species. \nPresenter 3: Shelbi Russell\, PhD\, UC Santa Cruz\, Ph.D.\, Organismic & Evol Bio\, Harvard\, PostDoc MCDB\, UC Santa Cruz \nDescription: Many animals harbor bacterial symbionts that manipulate host reproduction to enhance bacterial survival and transmission. Obligate intracellular symbionts\, such as Wolbachia pipientis\, are particularly adept at host manipulation\, influencing reproductive biology and even blocking viral replication. These bacterially induced traits have been harnessed in field studies to control mosquito populations and limit the spread of human pathogens like Dengue and Zika viruses. Despite these promising applications\, the molecular mechanisms underlying Wolbachia’s interactions with host cells remain poorly understood. Furthermore\, even less is known about the implications of these symbionts spreading to non-target hosts in the ecosystem. Previous work from my lab tackled these questions in vivo: we discovered that the wMel strain of Wolbachia can enhance host fertility and we discovered that even extremely low rates of horizontal symbiont transmission among hosts can influence bacterial genome evolution. However\, in vivo systems offer limited resolution to identify the precise cellular mechanisms of fertility enhancement and the real-time genomic impacts of horizontal transmission. Here\, we use an in vitro Drosophila system to 1) identify the cell type-specific impacts of Wolbachia infection on host-microbe interactions and 2) characterize how strains interact within host tissues during mixed infections. This simplified\, easy to sample system enabled us to concentrate the effects of host cell type on Wolbachia gene expression and to control de novo strain infections and mixtures. Through these experiments\, we discovered that different host cell types induce differential Wolbachia gene expression that feeds back to alter host gene expression and epigenetic silencing. These findings have motivated on-going single cell RNAseq work to resolve the process at the single cell level\, during de novo infections. Results from the experimental mixed infections revealed highly reproducible strain and cell type-specific dynamics. We will leverage these discoveries to understand strain-specific tissue tropisms and how multiple strains can co-exist as superinfections in nature\, which will inform future biocontrol strategies. \nBio: Shelbi is an Assistant Professor in the Department of Biomolecular Engineering at UCSC. She started her lab in 2022\, after completing her PhD at Harvard University in 2016 and performing her postdoctoral work at UCSC. Her passion for studying symbiotic systems began as an undergraduate researcher at the University of Kansas describing new tapeworm species. She transitioned to studying the evolutionary genomics of bacterial-animal mutualisms in her PhD and was awarded the UC Chancellor’s Postdoctoral Fellowship and the NIH Career Development Award (K99) to test genomic hypotheses in the Wolbachia-Drosophila model system during her postdoc. As faculty\, she is working to learn how hosts and microbes function and evolve so we can engineer associations for biological control. She has authored 24 papers and obtained $2.75 million in funding. Her interdisciplinary training makes her uniquely qualified to lead these investigations and has enabled novel breakthroughs in our understanding of symbiont evolution and microbe-induced host phenotypes. \nHosted by: Professor Josh Stuart\, BME Department \nRoom: PSB-240

SUMMARY:Applied Microeconomics and Trade Seminar Series presents: Matt Pecenco
DESCRIPTION:Applied Microeconomics and Trade Seminar\nDate: Thursday\, November 6\, 2025\nTime: 1:40-3:00 p.m.\nLocation: E2-499\n\n \n\nSpeaker: Matt Pecenco\nTitle: Orlando Bravo Assistant Professor of Economics \nAffiliation: Brown University \nHost: Ariel Zucker \n \nSeminar title: Conviction\, Incarceration\, and Policy Effects in the Criminal Justice System\n \nABSTRACT:   The criminal justice system affects millions of Americans through criminal convictions and incarceration. In this paper\, we introduce a new method for credibly estimating the effects of both conviction and incarceration using randomly assigned judges as instruments for treatment. Misdemeanor convictions\, especially for defendants with a shorter criminal record\, cause an increase in the number of new offenses committed over the following five years. Incarceration on more serious felony charges\, in contrast\, reduces recidivism during the period of incapacitation\, but has no effect after release. Our method allows the researcher to isolate specific treatment effects of interest as well as estimate the effect of broader policies; we find that courts could reduce crime by dismissing marginal charges against defendants accused of misdemeanors\, with larger reductions among first-time defendants and those facing more serious charges.

SUMMARY:Applied Microeconomics and Trade Seminar Series presents: Giovanni Peri
DESCRIPTION:Applied Microeconomics and Trade Seminar\nDate: Thursday\, November 13\, 2025\nTime: 1:40-3:00 p.m.\nLocation: E2-499\n\n \n\nSpeaker: Giovanni Peri\nTitle: C. Bryan Cameron Distinguished Professor in International Economics \nAffiliation: UC Davis\nHost: Gueyon Kim\n \nSeminar title: How the1942 Japanese Exclusion Impacted U.S. Agriculture\n \nABSTRACT:  In the early 1940s\, Japanese American farmers and farm workers represented an important part of agriculture-specific human capital in the United States. In 1942 all those living in the “exclusion zone” along the WestCoastwereforcefully relocated to internment camps and most of them never returned to farming. Using county-level panel data from historical agricultural censuses and a triple-difference (DDD) estimation approach we find that\, by 1960\, counties in the exclusion zone experienced 12% lower cumulative growth in farm value for each percentage point loss of their 1940 share of Japanese farm workers\, relative to counties outside the exclusion zone. Farm revenues\, farm productivity\, adoption of high-value crops\, mechanization\, and farm wages were also correspondingly lower. Taken together\, these findings are consistent with Japanese farmers representing hard-to-replace human capital\, rather than replaceable labor\, in US agriculture.

SUMMARY:ECE 290 Seminar: Low-Power and Miniaturized Medical Electronics for in vivo Localization and Tracking
DESCRIPTION:Presenter: Dr. Saransh Sharma\, Postdoctoral Scholar\, MIT \nDescription: Accurate in vivo localization of medical devices is central to applications ranging from ingestible pills in the GI tract to endovascular and minimally invasive procedures. However\, current clinical methods rely on endoscopy or repeated ionizing imaging (CT/X-ray)\, and are poorly suited for continuous or out-of-hospital use. In this talk\, I will present a radiation-free platform for high-precision localization of wireless miniaturized devices in vivo\, using engineered magnetic field gradients. We design battery-less ingestible microdevices that measure and transmit their local magnetic field\, while planar coils generate monotonically varying fields in X\, Y\, and Z. This architecture uniquely encodes spatial position and achieves <100 μm 3D accuracy—to our knowledge\, the highest reported. We then translate this to in vivo large-animal studies to localize ingestible devices in the GI tract in real time with mm-scale resolution\, without radiation or hospital-grade imaging. This enables continuous monitoring relevant to constipation\, incontinence\, motility disorders\, medication adherence\, and quantitative GI transit-time. Next\, I will show how this platform generalizes to surgical navigation. By embedding the same localization architecture into catheters and guidewires\, we can track device position without fluoroscopy\, offering a pathway toward image-free vascular navigation and minimally invasive interventions. Finally\, to further shrink devices and power\, I developed a monolithic 3D magnetic sensor in 65 nm CMOS (4 mm²\, 14.8 μW\, <10 μT_rms noise). This fully CMOS-compatible architecture enables high-sensitivity magnetic sensing at μW power\, and can serve as the core for future miniaturized\, radiation-free localization systems. \nBio: Dr. Saransh Sharma received the B.Tech. degree in Electronics and Electrical Communication Engineering from the Indian Institute of Technology (IIT)\, Kharagpur\, India\, in 2017\, and the M.S. and Ph.D. degrees in Electrical Engineering from the California Institute of Technology (Caltech)\, Pasadena\, CA\, USA\, in 2018 and 2023\, respectively. He is currently a postdoctoral research scholar at the Massachusetts Institute of Technology (MIT)\, Cambridge\, USA\, working on low-power analog and mixed-signal integrated circuits and system design for bio-medical applications. Dr. Sharma was a recipient of the Wilts Prize and the Demetriades-Tsafka-Kokkalis Award for outstanding Ph.D. thesis in Electrical Engineering\, Biotechnology and related fields at Caltech\, Lewis Winner Award for outstanding paper at ISSCC 2024\, Best Student Paper Award at CICC 2025\, Charles Lee Powell Fellowship at Caltech\, and Excellence in Mentorship Award at Caltech for mentoring undergraduate and graduate students. \nHosted by: Professor Soumya Bose\, ECE Department \nZoom Link: https://ucsc.zoom.us/j/97975378707?pwd=ljcgaCfhMmhZ88Vt5dqQUBVQRjehOx.1

SUMMARY:Macroeconomics & International Finance Seminar Series Presents: Yuriy Gorodnichenko
DESCRIPTION:Macroeconomics and International Finance Seminar\nDate: Tuesday\, November 18\, 2025\nTime: 1:40-3:00 p.m.\nLocation: E2-499\n\n \n\nSpeaker: Yuriy Gorodnichenko\nTitle: Quantedge Presidential Professor of Economics\nAffiliation: UC Berkeley\nHost: Pascal Michaillat\n \nSeminar title:  How costly are business cycle volatility and inflation? A Vox Populi approach\n \nABSTRACT:  Using surveys of households across thirteen countries\, we study how much individuals would be willing to pay to eliminate business cycles. These direct estimates are much higher than traditional measures following Lucas (2003): on average\, households would be prepared to sacrifice around 5-6% of their lifetime consumption eliminate business cycle fluctuations. A similar result holds for inflation: to bring inflation to their desired rate\, individuals would be willing to sacrifice around 5% of their consumption. Willingness to pay to eliminate business cycles and inflation is generally higher for those whose consumption is more pro-cyclical\, those who are more uncertain about the economic outlook\, and those who live in countries with greater historical volatility.

SUMMARY:AM Seminar: Linear Stochastic Emulators of the Ocean Circulation based on Balanced Truncation: A Caution\, perhaps\, for Machine Learning?
DESCRIPTION:Presenter: Professor Andy Moore\, UCSC Ocean Sciences \nDescription: Linear inverse models have enjoyed considerable popularity in the geosciences\, particularly in the arena of climate research and climate prediction\, for several decades as a straightforward approach to dimension reduction and streamlining computational efficiency. The most common approach is to truncate the system by retaining the leading Empirical Orthogonal Functions (EOFs) which represent the left singular vectors of the transition matrix. While singular value decomposition is the best low rank approximation of the transition matrix\, ignoring information contained in the right singular vectors\, as is commonly done in linear inverse models\, has consequences for the dynamics that approximate the system. Dimension reduction based on balanced truncation simultaneously preserves information from the right and left singular vectors. This talk will review some of these ideas and present examples from the ocean. Since EOF decomposition is quite commonly used for dimension reduction in some machine learning approaches\, there may be some lessons here for the machine learning community to consider. \nBio: Professor at UCSC since 2016. \nHosted by: Professor Julie Simons

SUMMARY:Macroeconomics & International Finance Seminar Series Presents: Helen Popper
DESCRIPTION:Macroeconomics and International Finance Seminar\nDate: Tuesday\, November 25\, 2025\nTime: 1:40-3:00 p.m.\nLocation: E2-499\n\n \n\nSpeaker: Helen Popper\nTitle: Professor of Economics\nAffiliation: Santa Clara University \nHost: Galina Hale\n \nSeminar title:  Artificial Intelligence and Macroeconomic Dynamics: Growth\, Pricing\, and Distribution\n \nABSTRACT:  This paper builds a simple general equilibrium model in which an AI producer is a monopolist who both learns by doing and uses AI recursively as an input. These mechanisms link today’s scale to tomorrow’s costs\, so pricing is dynamic: the firm sets a price below the static monopoly benchmark to expand capacity and speed learning. Final goods are produced by monopolistic competitors with constant returns to scale each period. We first use Cobb–Douglas technologies to solve for a generalized balanced growth path that pins down the condition for stable\, nonexplosive growth. On this path\, AI output grows faster than final output\, the relative price of AI falls persistently\, real wages rise with overall output\, and the specialized–to–nonspecialized wage ratio is flat. We then analyze CES versions of both sectors and derive a closed form effective demand elasticity for AI that combines input substitution in production with final-goods market substitution across varieties. Finally\, simulations link adoption and distribution to elasticities\, and they allow us to explore the dynamics. When final-goods inputs are complements\, adoption is learning-first and capital-light before scaling; when they are substitutes\, adoption is scale-first and the two-phase pattern attenuates. On the distribution side\, the specialized–to–nonspecialized wage premium is lowest with complements and rises with substitutes. Greater substitutability in AI production amplifies these patterns without changing their sign.

SUMMARY:AM Seminar: Denoising: A Powerful Building Block for Imaging\, Inverse Problems and Machine Learning
DESCRIPTION:Presenter: Peyman Milanfar\, Distinguished Scientist\, Google \nDescription: Denoising\, the process of reducing random fluctuations in a signal to emphasize essential patterns\, has been a fundamental problem of interest since the dawn of modern scientific inquiry. Recent denoising techniques\, particularly in imaging\, have achieved remarkable success\, nearing theoretical limits by some measures. Yet\, despite tens of thousands of research papers\, the wide-ranging applications of denoising beyond noise removal have not been fully recognized. This is partly due to the vast and diverse literature\, making a clear overview challenging. This article aims to address this gap. We present a clarifying perspective on denoisers\, their structure and their desired properties. We emphasize the increasing importance of denoising and showcase its evolution into an essential building block for complex tasks in imaging\, inverse problems and machine learning. Despite its long history\, the community continues to uncover unexpected and groundbreaking uses for denoising\, further solidifying its place as a cornerstone of scientific and engineering practice. \nBio: Peyman is a Distinguished Scientist at Google\, where he leads the Computational Imaging team. Prior to this\, he was a Professor of Electrical Engineering at UC Santa Cruz for 15 years\, two of those as Associate Dean for Research. From 2012-2014 he was on leave at Google-x\, where he helped develop the imaging pipeline for Google Glass. Over the last decade\, Peyman’s team at Google has developed several core imaging technologies that are used in many products. Among these are the zoom pipeline for the Pixel phones\, which includes the multi-frame super-resolution (Super Res Zoom) pipeline\, and several generations of state of the art digital upscaling algorithms. Most recently\, his team led the development of Pro Res Zoom\, and Unblur\, features launched in Pixel 10 devices and Google Photos. Peyman received his undergraduate education in electrical engineering and mathematics from the UC Berkeley\, and the MS and PhD degrees in electrical engineering from MIT. He holds more than two dozen patents. He founded MotionDSP\, which was acquired by Cubic Inc. Along with his students and colleagues\, his research work has had deep impact in several areas of computational imaging\, and applications of AI thereto – including the introduction of adaptive kernel regression to imaging; pioneering use of learning for fast\, content-adaptive image upscaling (RAISR); Neural Image quality Assessment (NIMA)\, Regularization by Denoising (RED); and most recently (2024) Inversion by Direct Iteration (InDI). All of these works have been recognized with best paper awards. He’s been a Distinguished Lecturer of the IEEE Signal Processing Society\, and is a Fellow of the IEEE “for contributions to inverse problems and super-resolution in imaging” \nHosted by: Professor Julie Simons\, Applied Mathematics \nZoom link: https://ucsc.zoom.us/j/93681175800?pwd=bgfPLQpTzs5PG4z3Qo2zbvMMScMAwn.1 \nMeeting ID: 936 8117 5800\nPasscode: 609643

SUMMARY:When Less is More: Applications of Type-Based Underapproximate Reasoning
DESCRIPTION:Presenter: Suresh Jagganathan\, Purdue University\n\n\nAbstract:\nUnlike program verifiers\, symbolic execution and property-based testing tools underapproximate program behavior: they aim to report only real bugs (no false positives)\, at the cost of potentially missing some (false negatives). Recent work has sought to place such tools on a more formal footing\, primarily through the development of incorrectness logics that capture a program’s ‘must’ rather than ‘may’ behavior. This talk explores how to transplant these ideas of underapproximation into an expressive refinement type system. Our development enables us to:\n\n(a) Typecheck the completeness of property-based testing (PBT) generators\, ensuring that a well-typed generator produces all values (i.e.\, fully covers) its output type;\n\n(b) Synthesize effectful generators by extending the type system to model underapproximations of sequences of effects rather than just values; and\n\n(c) Guide symbolic execution in effectful functional programs\, prioritizing execution paths capable of falsifying data structure safety properties.\n\nOur results demonstrate that viewing types through the lens of underapproximation offers a principled foundation for designing\, implementing\, and reasoning about program analyzers and test generators\, significantly improving their reliability and practical utility in the process.\n\n\nBio:\nSuresh Jagannathan is the Samuel D. Conte Professor of Computer Science at Purdue University. His interests span functional programming\, program verification\, distributed and concurrent systems\, and trustworthy machine learning. In recent years\, he has spent time as an Amazon Scholar\, a program manager at the Information Innovoation Office (I2O) at DARPA\, and a visiting researcher at the University of Cambridge. He serves an Associate Editor of ACM TOPLAS\, and has served as both General and PC Chair of POPL (ACM Symposium on Programming Languages).\n\n\nHosted by: Professor Mohsen Lesani\n\n\nLocation: E2-180\n*Refreshments such as coffee and pastries will be provided\n\n\n\nZoom: https://ucsc.zoom.us/j/93445911992?pwd=YkJ2TQtF79h0PcNXbEcpZLbpK0coiY.1&jst=3

SUMMARY:Applied Microeconomics and Trade Seminar Series presents: Matt Weinberg
DESCRIPTION:Applied Microeconomics and Trade Seminar\nDate: Wednesday\, December 3\, 2025\nTime: 11:50am – 1:10 p.m.\nLocation: E2-499\n\n \n\nSpeaker: Matt Weinberg \nTitle: Professor of Economics \nAffiliation: Ohio State University\nHost: Jon Robinson\n \nSeminar title: Oligopsony and Collective Bargaining: Evidence from K-12 Teachers \n\nABSTRACT:  Employers facing limited labor market competition may suppress wages below socially optimal levels. Unions can counteract this wage suppression through collective bargaining\, though the may also push wages above the socially optimal level. To assess these forces\, we estimate a structural model of labor supply\, labor demand\, and Nashin-Nash bargaining over wages between teacher unions and school districts in Pennsylvania’s K-12 public school system from 2013 to 2020. Using the estimated parameters\, we compare negotiated equilibrium wages and employment to the pure oligopsony scenario and the social planner scenario. On average\, pure oligopsony reduces wages 16 percent below the social optimum\, while collective bargaining raises wages by 9 percent above the optimum. This average masks substantial district-level heterogeneity driven by variation in bargaining power. Twenty-seven percent of schools have negotiated salaries below the social optimum due to cross-district externalities\, where high salaries at one school lead to hiring reductions\, which increase labor supply in competing districts.

SUMMARY:BME 280B Seminar: Gali Bai & David Haussler
DESCRIPTION:Presenter 1: Gali Bai\, BME/PBSE Doctoral Candidate\, Brooks Lab\, UC Santa Cruz \nTitle 1: Dissecting the contribution of chromatin accessibility to RNA transcription and processing with long-read sequencing \nDescription: Although all cells in an organism share the same genomic sequence\, transcriptional programs vary dramatically across cell types. This diversity is governed by epigenetic regulation involving the coordinated activities of chromatin remodelers\, histone modifiers\, and histone chaperones that precisely modulate chromatin accessibility. While previous studies have shown that chromatin accessibility at DNase I–hypersensitive sites such as promoters and enhancers is closely associated with gene expression\, much less is known about how chromatin influences transcription and RNA processing. To study how chromatin regulates RNA processing\, we perturbed yeast chromatin accessibility by deleting two highly conserved chromatin remodelers ISW1 and CHD1. With Oxford Nanopore long-read sequencing\, we profiled nascent RNA\, full-length mRNA\, and chromatin fibers in wild-type and chd1 isw1 double-mutant yeast cells. Loss of ISW1 and CHD1 led to increased chromatin accessibility within intragenic regions\, accompanied by aberrant transcription initiation. Leveraging long-read data\, we associated distinct chromatin states with specific RNA processing events and isoform expression outcomes. Despite a similar level of chromatin perturbations across the genome\, genes with low baseline expression showed extensive transcriptional reprogramming\, whereas highly expressed genes remained largely unaffected. These discrepancies can be partially explained by differences in the enrichment of transcription initiation motifs. In intron-containing genes\, loss of ISW1 and CHD1 reduced splicing efficiency and increased intron retention\, likely due to disrupted RNAPII elongation in the double mutant. Together\, our findings highlight the crucial role of ATP-dependent chromatin remodelers in maintaining nucleosome organization and coordinating co-transcriptional RNA processing. \nPresenter 2: David Haussler\, Distinguished Professor\, UC Santa Cruz \nTitle 2: Brain Organoids \nBio: Haussler received his PhD in computer science from the University of Colorado at Boulder. He is a member of the National Academy of Sciences\, the National Academy of Engineering\, the American Academy of Arts and Sciences and a fellow of AAAS and AAAI.

SUMMARY:Behavioral\, Econometrics and Theory Seminar Series Presents: Jacopo Magnani
DESCRIPTION:Economics Behavioral\, Econometrics\, & Theory Seminar\nDate: Thursday\, December 4\, 2025\nTime: 1:40-3:00 p.m.\nLocation: E2-499\n\n \n\nSpeaker: Jacopo Magnani \nTitle:  Associate Professor of Economics \nAffiliation: Norwegian University of Science and Technology\, visiting Caltech\nHost: Kristian Lopez Vargas\n \nSeminar title: Behavioral Limits to Complete Markets\n \nABSTRACT:  Standard economic theory predicts that individuals should prefer complete markets to incomplete markets\, as the former allow state-contingent claims for every possible outcome. Yet real-world markets remain incomplete\, and the demand-side origins of the phenomenon are poorly understood. We develop an experimental framework to examine whether investors may themselves prefer incomplete markets\, and highlight two potential mechanisms: preference instability\, which exposes agents to greater regret or temptation in complete markets\, and complexity costs\, which arise because higher dimensionality increases cognitive effort and errors. In our experiment\, participants consistently reveal a preference for in complete markets\, contradicting the rational benchmark. Comparing homegrown and induced-preference treatments\, we find no evidence that this behavior is driven by preference instability. Instead\, utility losses\, response times\, and subjective ratings indicate that complexity costs drive the preference for incompleteness. Structural estimation confirms that complete markets are several times more complex than incomplete ones\, providing a behavioral foundation for market incompleteness.

SUMMARY:CSE Colloquium: Making Systems Secure with Information Flow
DESCRIPTION:Presenter: Andrew Myers\, Cornell University\n\nAbstract:\nModern civilization depends on complex\, interconnected software systems that must safeguard trustworthy or private data. We have ever-growing mountains of code yet lack principled ways to build large systems that are secure. What is missing is a way to securely build these systems compositionally: module by module and layer by layer. Information flow control\, enforced throughout software and hardware\, offers a plausible way to achieve compositional security\, and is increasingly being used by industry. I describe how my research group has incorporated information-flow security into various languages and systems: hardware architectures resilient to timing and speculation attacks\, smart contracts\, and automatically synthesized cryptographic and distributed protocols. Information flow is inherently compositional and makes possible strong\, provable security guarantees that can be connected to cryptographic security definitions. Importantly\, it also guides developers during the design process\, exposing security-critical decisions up front. \nBio:\nAndrew Myers is the Class of 1912 Professor of Engineering in the Department of Computer Science at Cornell University. He received his Ph.D. in Electrical Engineering and Computer Science from MIT\, advised by Barbara Liskov. His research interests include programming languages\, computer security\, and distributed and persistent programming systems. His work on computer security has focused on practical\, sound\, expressive languages and systems for enforcing information security. Myers is an ACM Fellow and has authored several award-winning papers. He currently serves as the chair of the ACM SIGPLAN Executive Committee. \nHosted By: Professor Mohsen Lesani \nLocation: Engineering 2\, E2-180 \nZoom: https://ucsc.zoom.us/j/97682837116?pwd=WZBzhJY4p7rTZshqglmOs6xBtBasbE.1&jst=3

SUMMARY:CM Seminar - "How Technology-Mediated Food Interactions Support Family Connection and Routine Reconstruction"
DESCRIPTION:Presented by: Aswati Panicker \nDescription: “In this talk\, I draw on work in human-food interaction (HFI) to examine how food can serve as a rich interaction medium for connection and routine reconstruction in long-distance families. I highlight insights from three of my studies that explore this question across different technological forms. First\, I discuss how families navigate shifting meanings of “healthy eating” during life transitions\, and the tensions that arise when disclosing new goals and priorities in health-sharing or tracking tools. Second\, I show how family members expressed hesitations\, value conflicts\, and visions for cultural or playful moments when imagining embodied technology such as a social robot within their domestic spaces. Third\, through a mobile app probe for teaching food knowledge and recipes\, I uncover the subtleties of how family members seek to initiate\, learn\, guide\, or be guided through everyday food practices. Throughout\, I outline design implications and close by reflecting on how technology-mediated food interactions might extend to other contexts and routines beyond family life.” \nBio: Aswati Panicker is a postdoctoral scholar at the University of California\, Santa Cruz\, working with Prof. Christina Chung. Her research is at the intersection of HCI and CSCW\, focusing on how technologies are designed and used in social and health-related contexts. She takes a human-centered\, participatory approach and draws on theories from family studies and sociology in her work. She earned her PhD in Informatics from Indiana University Bloomington in July 2025.

SUMMARY:AM Seminar with Dr. Truong Vu
DESCRIPTION:Presenter: Dr. Truong Vu\, IPAM and MSU \nDescription: We present a framework for the gradient flow of sharp-interface surface energies that couple to embedded curvature active agents. We use a penalty method to develop families of locally incompressible gradient flows that couple interface stretching or compression to local flux of interfacial mass. We establish the convergence of the penalty method to an incompressible flow both formally for a broad family of surface energies and rigorously for a more narrow class of surface energies. \nBio: Dr. Vu received a Ph.D. in Applied Mathematics from the Department of Mathematics\, Statistics\, and Computer Science at University of Illinois at Chicago. Dr. Vu is currently a Postdoctoral Fellow at the Institute for Pure and Applied Mathematics (UCLA) and a visiting faculty in the Department of Mathematics at Michigan State University. \nHosted by: Applied Mathematics

SUMMARY:BME 280B Seminar: Nature’s Miniature Masterpieces - Nanobodies as Small but Mighty Antibodies for the next Pandemic
DESCRIPTION:Presenter: Katja Hanack\, Founder and CEO\, New/Era/Mabs \nDescription: Nanobodies combine remarkable simplicity with surprising power. Their small size allows them to reach targets that remain inaccessible to conventional antibodies\, while maintaining high specificity and stability. Their compact architecture allows them to access targets that conventional antibodies cannot reach\, yet they preserve the specificity and power that make antibody therapeutics so transformative. In this talk I will introduce the science behind selma\, a cell based discovery platform developed over more than a decade to rapidly identify high quality antibodies and nanobodies. I will explore why these tiny binders matter\, how they differ from classical antibodies\, and what their unique biology enables for diagnostics and therapeutics. \nThe presentation will conclude with my current project on immune infrastructure and how pre validated nanobody archives can shift the pandemic response from a reactive model to proactive preparedness for future outbreaks. \nBio: Katja Hanack\, PhD\, MBA\, is the Founder and CEO of new/era/mabs and a leading expert in antibody discovery for diagnostic and therapeutic applications\, with a particular focus on nanobody technologies. With more than 20 years of experience\, she has developed pioneering platforms that enable the efficient generation and selection of next-generation monoclonal antibodies and nanobodies. She holds a Biology degree from Humboldt University of Berlin and a PhD in Biotechnology from the University of Potsdam. As a former Professor of Biochemistry and Biology at the University of Potsdam\, she built and led a research group of 25 scientists\, secured over €16 million in external funding\, and authored more than 40 peer-reviewed publications. Since 2017\, Dr. Hanack has contributed to translational innovation as an industrial advisor for SPARK Stanford and SPARK Berlin\, supporting academic teams in bringing biomedical discoveries to patients. \nHosted by: Professor Rebecca Dubois\, BME Department

SUMMARY:Kathleen Schmidt: Sequential Experimental Design for Materials Strength Model Calibration
DESCRIPTION:Presenter: Katie Schmidt\, UQ & Optimization Group Leader\, Lawrence Livermore National Laboratory \nDescription: Due to the time and expense associated with physical experiments\, there is significant interest in optimal selection of the conditions for future experiments. Selection based on reduction in parameter uncertainty provides a natural path forward. We consider this type of optimal sequential design in the context of Bayesian calibration of materials strength models with the strength model characterizing the evolving resistance of a material to permanent strain. This problem is particularly challenging because different types of experiments and associated diagnostics are employed across strain rate regimes. For lower-strain-rate experiments\, stress-strain curves can be measured directly. For higher-strain-rate experiments\, strength must be inferred (e.g.\, from the deformation of a cylinder of material in a Taylor cylinder experiment). We employ data fusion in our sequential design methodology to incorporate these multiple experimental modalities. \nLLNL-ABS-835231 This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. \nBio: Katie Schmidt is the UQ & Optimization Group Leader at Lawrence Livermore National Laboratory. She joined LLNL in 2016 after earning a PhD in Applied Mathematics from North Carolina State University. During her time at the lab\, Katie has been involved in a variety of uncertainty quantification problems related to national security as well as outreach and education through LLNL’s Data Science Institute. Her research interests include mixed-effects models\, Bayesian inference\, sequential design\, and sensitivity analysis. \nHosted by: Statistics Department

SUMMARY:AM Seminar: Science in the Age of Foundation Models
DESCRIPTION:Presenter: Dr. Danielle Robinson\, AWS AI \nDescription: In this talk\, I will discuss the large impact of foundation models within the sciences with a particular focus on the importance of physical constraints and uncertainty quantification. First\, I will detail our novel ProbConserv framework for enforcing hard constraints within black-box deep learning models. ProbConserv provides uncertainty quantification\, and can be used to enforce conservation law constraints as well as other nonlinear constraints. Next\, I will discuss its extensions to ensembles of Neural Operators and out-of-distribution (OOD) estimations\, as well as how it can be used in constrained generative modeling of PDEs. I will then show applications of our work in computational fluid dynamics (CFD)\, including weather forecasting\, aerodynamics and chaotic systems. Lastly\, I will conclude with a forward-looking view of the next steps for designing a physics foundation model that can be applied across various types of flows\, geometries and boundary conditions\, and what is needed for such a model to be developed. \n\n\n\n\n\n\n\n\n\nBio: Danielle Maddix Robinson is a Senior Applied Scientist in the Machine Learning Forecasting Group within AWS AI. She graduated with her PhD in Computational and Mathematical Engineering from the Institute of Computational and Mathematical Engineering (ICME) at Stanford University. She was advised by Professor Margot Gerritsen and developed robust numerical methods to remove spurious temporal oscillations in the degenerate nonlinear Generalized Porous Medium Equation. She is passionate about the underlying numerical analysis\, linear algebra and optimization methods behind numerical PDEs and applying these techniques to deep learning. During her PhD\, she also did an internship at NVIDIA with Joe Eaton and Alex Fender\, and implemented an efficient and load-balanced sparse matrix vector multiplication (spmv) in cuSPARSE and nvGRAPH libraries. She is excited to be back at NVIDIA today. After graduating\, Danielle joined AWS in 2018\, and has been working on developing statistical and deep learning foundation models for time series forecasting including Chronos. Over the last several years\, she has been leading the research initiative on developing models for physics-constrained machine learning for scientific computing on the DeepEarth team. In particular\, she has researched how to apply ideas from numerical methods\, e.g.\, finite volume schemes\, to improve the accuracy of black-box ML models for PDEs with applications to ocean and climate models\, aerodynamics and chaotic systems. \n\n\n\nHosted by: Applied Mathematics\n\n\n\nLink: https://ucsc.zoom.us/j/96136632376?pwd=yb27lop8mnhnsairAPgezmVJZzFb74.1.

SUMMARY:Macroeconomics & International Finance Seminar Series Presents: Dean Corbae
DESCRIPTION:Macroeconomics and International Finance Seminar\nDate: Tuesday\, January 13\, 2026\nTime: 1:40-3:00 p.m.\nLocation: E2-499\n\n \n\nSpeaker: Dean Corbae\nTitle: William Sellery Trukenbrod Chair in Finance\nAffiliation: University of Wisconsin – Madison\nHost: Grace Gu Steadmon\n \nSeminar title:  A Quantitative Model of Bank Merger Dynamics\n \n\nABSTRACT: \nWe develop a simple model of the bank merger process to study the rise in bank concentration following the deregulation of bank branching in the Riegle-Neal Act of 1994. Motivated by the data where currently 10 (dominant) banks have over 55 percent of the U.S. deposit market share while the remaining over 4000 (fringe) banks cover the rest\, we apply a dominant-fringe framework with a merger stage to model the rise in concentration following the change in regulation making interstate branching possible. First\, we study the effect of the merger wave on competition\, efficiency\, and stability of the banking industry. Then we use our model to understand the interaction between regulatory and monetary policy. Specifically\, how has the bank lending channel of monetary policy been affected by rising concentration; has it amplified or dampened the effectiveness of monetary policy? How might monetary policy itself contribute to mergers and rising concentration?

SUMMARY:Applied Microeconomics and Trade Seminar Series Presents: Olivia Bordeu
DESCRIPTION:Applied Microeconomics and Trade Seminar\nDate: Thursday\, January 15\, 2026\nTime: 1:40 – 3:00 p.m.\nLocation: E2-499\n\n \n\nSpeaker: Olivia Bordeu \nTitle: Assistant Professor of Economics \nAffiliation: University of California\, Berkeley  \nHost: Jeremy West \nSeminar title: Bank Branches and the Allocation of Capital across Cities\n\nABSTRACT: We study how banking market structure and branch networks shape the spatial mobility of capital. Using administrative loan-level data from Chile\, we show that bank-level deposit shocks lead receiving banks to increase lending and lower interest rates relative to other banks. Interest rate reductions are concentrated in cities where the bank has a small market share\, consistent with local market power. We develop and estimate a quantitative spatial model with multi-city banks\, oligopolistic local credit markets\, and frictions in interbank lending. These channels lead to spatial dispersion in interest rates and the marginal productivity of physical capital\, reducing GDP. Interbank frictions reduce steady-state GDP by 0.04%\, while spatial variation in loan markups reduces GDP by 0.5%. Bank mergers improve financial integration between cities but reduce competition\, generating heterogeneous welfare effects that depend on the merging banks’ geographic overlap.

SUMMARY:Behavioral\, Econometrics and Theory Seminar Series Presents: Roberto Corrao
DESCRIPTION:Economics Behavioral\, Econometrics\, & Theory Seminar\nDate: Tuesday\, January 20\, 2026\nTime: 1:40-3:00 p.m.\nLocation: E2-499\n\n \n\nSpeaker: Roberto Corrao\nTitle:  Assistant Professor of Economics \nAffiliation:  Stanford University\nHost: Gerelt Tserenjigmid\n \nSeminar title: Contractibility Design\n \nABSTRACT: \nWe introduce a model of incentive contracting in which the principal\, in addition to\nwriting contracts\, must engage in contractibility design: creating an evidence structure\nthat allows them to prove when the agent has breached the contract. Designing an\nevidence structure entails both (i) front-end costs borne ex ante\, such as those of\ndrafting contracts\, and (ii) back-end costs borne ex post\, such as those of generating\nevidence. We find that\, under even small front-end costs\, optimal contracts are coarse\,\nspecifying finitely many contingencies out of a continuum of possibilities. In contrast\,\nunder even large back-end costs\, optimal contracts are complete. Applied to the design\nof procurement contracts\, our results rationalize: (i) the discreteness of contracts\, (ii)\nthe presence of similarly vague contracts in low-stakes and high-stakes settings\, and\n(iii) the discontinuous adjustment of contracts to changes in the economic environment.
