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:CM Seminar: "Playful Design to Empower Climate Adaptation - What are we missing for real-life impact?"
DESCRIPTION:Presented by: Linda Hirsch \n  \nDescription: “Games and playful interventions have been researched to increase awareness of climate change impacts and educate about mitigation and adaptation measures. However\, besides increased awareness\, what real-life impact and adapted behaviors can we actually observe from such interventions? In this talk\, I will reflect on the differences between short-term and long-term community empowerment through playful interventions and discuss three outstanding research directions for designing real-life climate adaptation.” \nBio: Linda Hirsch is a postdoctoral researcher at Computational Media\, UCSC\, under the supervision of Katherine Isbister. She holds a magna cum laude doctoral degree in Media Informatics from LMU Munich\, Germany. Her research focuses on exploring\, conceptualizing\, and creating meaningful human-environment interactions to strengthen communities toward increased climate resilience. Linda Hirsch has been an elected executive committee member of the German group “Be-greifbare Interaktion” since 2021\, an expert research group within the German Society of Information Technology regarding topics for tangible and embedded interfaces.  \n  \nHosted by: Professor Katherine Isbister \nWhen: Monday\, November 17\, 2025 from 12:30PM to 1:30PM \nLocation:  \nIN-PERSON @ UCSC Main Campus\, E2-280. \nViewing room @ SVC 3212.  \nLUNCH WILL BE PROVIDED AT BOTH LOCATIONS!

SUMMARY:AM Seminar: Dynamo Action Inside the Giant Planets
DESCRIPTION:Presenter: Dr. Paula Wulff\, UCLA \nDescription: Our solar system hosts six unique planetary magnetic fields. Intrinsic magnetic fields are generated deep inside planets by dynamo action. This process requires regions of electrically conducting material and energy sources to maintain the dynamo. Thus\, we can learn about the deep interiors of planets\, including their structures and dynamics\, by investigating their magnetic fields. In this talk\, I’ll explore some of the interesting questions and possible answers about planetary interiors that have come from studies of planetary magnetism\, in particular through 3-dimensional magnetohydrodynamic simulations. \nBio: Paula Wulff completed her PhD with Uli Christensen at the Max-Planck-Institute for Solar System Science\, in Goettingen\, Germany\, after her undergrad at Cambridge (UK). While working with Uli\, she studied zonal flows on Gas Giants\, in particular on Jupiter. She used the gravity measurements made by Juno to infer their depth\, and numerical modelling to investigate their truncation mechanism at depth. After her PhD\, she moved to California to work with Hao Cao and Jon Aurnou at UCLA’s EPSS department. During the postdoc she has continued to work on 3-D MHD modelling to study the dynamo mechanisms in the interiors of various planets in our solar system. \nHosted by: Professor Julie Simons

SUMMARY:Statistics Seminar: Beyond the Average Treatment Effect: Causal Mediation Methods for Understanding Intervention Mechanisms
DESCRIPTION:Presenter: Hanna Kim\, Assistant Professor\, Psychology Department\, UCSC \nDescription: Understanding how an intervention works is a central question in behavioral and social research\, following the demonstration of its overall effect. Traditional mediation analysis techniques often assume a homogeneous mechanism of effects\, overlooking both validity concerns and subgroup variation in causal pathways. In this talk\, I present a series of developments in causal mediation methods aimed at identifying and estimating natural direct and indirect effects\, addressing challenges such as unobserved confounding and heterogeneity across subpopulations. I illustrate these approaches using data from early childhood education programs and online course participation\, showing how causal mediation analysis can reveal diverse mechanisms of change. The talk concludes with current directions for integrating mixture modeling and clustered data analysis with causal inference to enhance both robustness and interpretability at the interface of statistics and applied research. \nBio: Hanna Kim is an Assistant Professor of Quantitative Psychology at the University of California\, Santa Cruz. Her research centers on advancing causal inference and mediation methods to investigate how educational programs influence child development and how effects differ across subpopulations. She also integrates latent variable modeling with dyadic data analysis to study interpersonal dynamics. Her work bridges psychology and statistics to address methodological challenges in applied research\, with publications in Psychological Methods\, Cancer Epidemiology\, Biomarkers & Prevention\, Journal of Substance Use and Addiction Treatment\, and the Asian Journal of Education. \n\n\n\n\n\nHosted by: Professor Paul Parker
