SUMMARY:Doganyigit\, K. (BMEB) - Reimagining the petri dish\, automated incubator-free organoid culture system for long term organoid maintenance and disease modeling
DESCRIPTION:Organoids offer strong in vitro models for studying development and disease; however\, traditional incubator-based culture methods hinder environmental regulation\, elevate evaporation rates\, and limit imaging and instrumentation access—restricting their effectiveness for prolonged\, physiologically relevant research. To address these challenges\, we created a compact\, automated culture system that eliminates the need for an incubator by integrating microfluidic recirculation with gas exchange inspired by artificial lungs in intensive care medicine. The system employs a fluid impermeable gas-exchange membrane along with an aqueous buffer to passively stabilize oxygen\, pH\, and osmolarity. Automated media transfer and integrated sensing enable consistent\, multi-week live imaging and accurate environmental control. \n\n   The First Aim of this proposal addresses the creation and execution of this organoid culture platform that does not require an incubator. In Aim 2\, I validate the system utilizing mouse cerebral cortex organoids grown in the system\, evaluating metabolic viability\, tissue structure\, and electrophysiological activity in comparison to shaker-incubator controls. I will also employ RNA sequencing to further analyze cell-type composition and transcriptional stress profiles. In Aim 3\, I will modify the platform to simulate the prenatal stroke penumbra by incorporating spatially localized hypoxia and hypoglycemia through pressure-modulated perfusion. Combining real-time hypoxia imaging with transcriptomic analysis to facilitate investigation of ischemic damage and recovery within a regulated organoid model. Overall\, this research seeks to create a flexible\, and physiologically appropriate culture system that enhances experimental access and facilitates a better environment for new models of organoid development and disease research. \nEvent Host: Kivilcim Doganyigit\, Ph.D Student\, Biomolecular Engineering & Bioinformatics \nAdvisor: David Haussler

SUMMARY:Mavrogiannakis\, A. (CSE) - Scalable Oblivious Databases and Systems
DESCRIPTION:Modern applications are increasingly designed with a strong emphasis on scalability and performance\, as systems are expected to process ever-growing volumes of data and deliver results with minimal latency. Techniques such as distributed architectures\, in-memory computation\, and optimized data structures are routinely adopted to meet these performance-driven demands. However\, in the pursuit of speed and efficiency\, security is often treated as a secondary concern or an afterthought. This oversight can lead to critical vulnerabilities\, as even the most performant systems remain fundamentally insecure if sensitive information can be leaked or exploited. As data becomes more valuable and privacy regulations grow stricter\, ensuring robust security measures is not merely desirable but strictly necessary—an essential requirement that must stand alongside scalability and performance as a first-class design goal. \nTo meet security requirements\, many applications adopt end-to-end encryption to protect data stored in the cloud. While this prevents external adversaries from accessing sensitive information\, prior work [CITE] has demonstrated that encryption alone is insufficient: an untrusted server can still exploit execution patterns and access behaviors to gradually reconstruct the underlying database in plaintext. As an alternative\, other applications rely on Trusted Execution Environments (TEEs)\, which offer strong guarantees through memory encryption\, isolation\, and integrity checks. TEEs are particularly appealing due to their ease of use and high performance\, often approaching that of non-encrypted systems. However\, TEEs are not without limitations [CITE]. They remain vulnerable to leakage-abuse attacks and side-channel vulnerabilities [CITE]\, which can undermine their security guarantees in practice. \nIn my research\, I combine TEEs with oblivious computation to achieve stronger security guarantees without sacrificing practicality. Specifically\, my work focuses on designing\, analyzing\, and implementing oblivious algorithms for databases and systems. A central theme of my research is bridging the gap between security and performance\, developing scalable algorithms that approach the efficiency of plaintext execution. For example\, in our first project\, Obliviator (to appear at USENIX Security ’25)\, we introduced oblivious implementations of fundamental database operators—such as filtering\, aggregation\, and joins—in a shared-memory setting\, achieving efficiency at scale on datasets up to hundreds of gigabytes. Building on this foundation\, our subsequent work extends these operators to distributed environments\, addressing challenges such as secure execution under weaker trust assumptions and reducing communication overhead\, both in terms of rounds and data exchanged. We also introduced frameworks that enable parallelism in oblivious computation\, further enhancing performance. My current work focuses on extending these techniques to multi-way joins\, where combining multiple tables introduces new challenges in both efficiency and security. In parallel\, I am exploring query optimization strategies tailored to the oblivious setting\, with the goal of pushing oblivious database systems closer to the performance of traditional plaintext systems. \nEvent Host: Apostolos Mavrogiannakis\, Ph.D Student\, Computer Science & Engineering
