    • MEAM Seminar: MEAM Faculty Showcase

    /
    Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

    Please join us on Tuesday, September 9 for an overview of research being done in the MEAM Department, hosted by MEAM Department Chair, Dr. Kevin Turner. This is an excellent opportunity for current graduate students to learn about the breadth of work being done in MEAM. The following faculty will be presenting (not in order […]

    ASSET Seminar: “Rethinking Test-Time Thinking: From Token-Level Rewards to Robust Generative Agents”

    /
    Amy Gutmann Hall, Room 414 3333 Chestnut Street, Philadelphia, United States

    We present a unified perspective on test-time thinking as a lens for improving generative AI agents through finer-grained reward modeling, data-centric reasoning, and robust alignment. Beginning with GenARM, we introduce an inductive bias for denser, token-level reward modeling that guides generation during decoding, enabling token-level alignment without retraining. While GenARM targets reward design, ThinkLite-VL focuses on the data […]

    Fall 2025 GRASP SFI: Tairan He, Carnegie Mellon University & NVIDIA, “Scalable Sim-to-Real Learning for General-Purpose Humanoid Skills”

    /
    Levine 307 3330 Walnut Street, Philadelphia, PA, United States

    This is a hybrid event with in-person attendance in Levine 307 and virtual attendance via Zoom.  ABSTRACT Humanoids represent the most versatile robotic platform, capable of walking, manipulating, and collaborating with people in human-centered environments. Yet, despite recent advances, building humanoids that can operate reliably in the real world remains a fundamental challenge. Progress has […]

    CBE Seminar: “Non-equilibrium Dynamics of Lipid Vesicles using Automated Flow Control” (Charles Schroeder, Princeton University)

    /
    Wu & Chen Auditorium

    Abstract: Vesicles are membrane-bound compartments that play a central role in biology. Despite recent progress, the dynamics of single- and multi-component lipid vesicles are not fully understood, particularly far from equilibrium where complex nonspherical shapes undergo large deformations in flow. In this talk, I will present recent work from our group on the non-equilibrium dynamics […]

    FOLDS seminar: Algorithmic stability for regression and classification

    /
    Amy Gutmann Hall, Room 414 3333 Chestnut Street, Philadelphia, United States

    In a supervised learning setting, a model fitting algorithm is unstable if small perturbations to the input (the training data) can often lead to large perturbations in the output (say, predictions returned by the fitted model). Algorithmic stability is a desirable property with many important implications such as generalization and robustness, but testing the stability […]

    ESE PhD Thesis Defense – “Design and Characterization of AlScN-Based Ferroelectric Devices for Non-Volatile Memory Applications”

    /
    Room 221, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

    Ferroelectric materials have emerged as promising candidates for next-generation non-volatile memory technologies due to their intrinsic remnant polarization and fast switching dynamics. Among them, aluminum scandium nitride (AlScN) stands out for its CMOS compatibility, low growth temperature, exceptional thermal stability and high remnant polarization compared to conventional perovskite and hafnia-based ferroelectrics. In this dissertation, I […]

    ESE PhD Thesis Defense – “Learning-based Safe and Robust Control for Multi-Agent Systems”

    /
    WYSIWYG

    AI-enabled systems have become ubiquitous and integral to safety-critical domains, e.g., autonomous vehicles and aerial robotics. Despite promising empirical results, decision-making processes for critical systems incorporating AI components require careful consideration, as failures may have catastrophic consequences. One key challenge is that various uncertainties will inevitably arise from system limitations, black-box models, or environmental factors, […]

    ESE PhD Thesis Defense – “Magnetostatic Surface Wave and Surface Acoustic Wave Devices for Tunable and Energy Efficient Radio Frequency Filters”

    /
    Greenberg Lounge (Room 114), Skirkanich Hall 210 South 33rd Street, Philadelphia, PA, United States

    Tunable and energy-efficient filters are key components in modern wireless communication, where RF front-end systems must operate across multiple frequency bands while minimizing power consumption. This thesis focuses on the design and fabrication of miniature, narrowband, tunable bandpass and bandstop filters based on magnetostatic waves (MSW) in yttrium iron garnet (YIG) waveguides. A zero-static-power magnetic […]

    MEAM Seminar: “Micro-surgical Tools for Dissecting Cells and Tissues”

    /
    Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

    Wound healing is an essential biological process for maintaining homeostasis and, ultimately, for survival. We investigate the mechanisms underlying extreme wound healing in Stentor coeruleus, a single-celled organism, capable of recovering from drastic membrane wounds exceeding half of the cell surface. This talk focuses on our recent effort on developing a microfluidic platform for the […]

    ASSET Seminar: “Symbolic Reasoning in the Age of Large Language Models”

    /
    Amy Gutmann Hall, Room 414 3333 Chestnut Street, Philadelphia, United States

    Today, reasoning is commonly interpreted as large language models generating chains of thought. Yet historically, AI reasoning had a very different meaning: executing algorithms that manipulated symbols to perform logical or probabilistic deduction and derive definite answers to questions about knowledge. In this talk, I show that such old-fashioned ideas are very relevant to reasoning […]
