    • ESE PhD Thesis Defense: “A Dynamical Systems Perspective on Optimization Algorithms”

    /
    Zoom - Meeting ID: 946 6798 0381

    The intersection of machine learning (ML) and dynamical systems and control (S&C) has become a prominent area of research in recent years. While most work applies ML to S&C problems, this dissertation explores the reverse direction: using S&C tools to address challenges in ML and optimization. This thesis is comprised of three parts: In part […]

    Innovative Approaches in Data-Driven Chemistry and Reaction Optimization

    /
    PICS Conference Room 534 - A Wing , 5th Floor 3401 Walnut Street, Philadelphia, PA, United States

    Research in the Zahrt group focuses on creating new tools to advance organic synthesis by integrating automation and machine learning workflows to enhance molecular function, reaction efficiency, and sustainability. We develop and use active learning strategies for catalyst design, reaction conditions, and other molecular properties. To accelerate the implementation of these algorithms, we pair them […]

    ESE PhD Thesis Defense: “Software-like Incremental Refinement on FPGA using Partial Reconfiguration”

    /
    Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

    To improve FPGA design productivity, our goal is to create a development experience for FPGAs that aligns closely with widely accepted software design principles. Software programmers quickly test their minimally completed design, identify the bottleneck, and incrementally refine the design. In FPGA design, however, such incremental refinement is not currently supported. (1) FPGA compilation is long, […]

    • MSE Doctoral Dissertation Defense: “Polymer Infiltrated Nanoporous Gold: Kinetics and Optical Properties of Novel Polymer Nanocomposites” (Weiwei Kong)

    /
    LRSM Reading Room 3231 Walnut St., Philadelphia, PA, United States

    Abstract: One of the biggest challenges in the field of polymer nanocomposites (PNCs) is to disperse high nanofiller loadings into the polymeric matrix. The high loading and uniform dispersion are limited by the unfavored polymer/nanofiller thermodynamics and the tendency for nanofiller to aggregate. In this thesis, these are circumvented by using nanoporous gold (NPG) as […]

    CBE Doctoral Dissertation Defense: “Utilization of Atomic Layer Deposition for Heterogeneous Catalysis in Biomass Upgrading Applications” (Mengjie Fan)

    /
    Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

    Abstract: The need for sustainable energy sources has intensified interest in biomass upgrading, where biomass-derived feedstocks are transformed into fuels and valuable chemicals. A major challenge in biomass upgrading is the development of highly active, selective, and stable catalysts for complex reactions. Traditional synthesis methods often result in heterogeneous catalysts with poor dispersion of active […]

    MEAM Seminar: “Differentiable Algorithms for Non-differentiable Robotics: Dexterous Manipulation via Implicit Learning and Control”

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

    As we ask our robotic systems to become more capable, with the ultimate aim of deploying robots into complex and ever-changing scenarios, the vast space of potential tasks drives the need for flexibility and generalization. For all the promise of big-data machine learning, what will happen when robots deploy to our homes and workplaces and […]

    Fall 2024 GRASP Seminar: Anand Bhattad, Toyota Technological Institute at Chicago, “Are Generative Image Models Physically Grounded?”

    /
    Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

    *This seminar will be held in-person in Raisler Lounge as well as virtually via Zoom. ABSTRACT Computer vision has transformed from simple edge detection in the 1980s to modern generative models that generate uncannily realistic images: objects are in sensible places, lighting seems realistic, and textures appear accurate. But how do they achieve this understanding […]

    BE Fall 2024 Demos

    /
    Skirkanich 225

    The Department of Bioengineering Fall 2024 Student Demos. Location: The Stephenson Foundation Bio-Makerspace (aka the BE Labs) in Skirkanich Hall 225. BE 3090, aka BE MAD: Human-Cockroach Machine Interface. December 4th from 1:30-2:30 PM, and December 5th from 3:15-4:15. BE 4950 Senior Design: Minimum Viable Product. December 9th, 3:30-5:00 PM.

    ASSET Seminar: “Curious Embeddings, Hazy Oracles, and the Path to Safe, Cooperative AI”

    /
    Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

    Abstract: Cooperation through safe and trustworthy communication and interaction is fundamental to how human teams accomplish complex tasks. Yet, despite significant--and sometimes revolutionary--advances in AI, we have barely begun to unlock the potential of safe, cooperative AI. This may stem from our limited understanding of how multimodal, large-scale AI models function, the one-sided nature of […]

    Fall 2024 GRASP SFI: Dylan Shell, Texas A&M University, “Robot situatedness and information requirements for tasks”

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

    This will be a hybrid event with in-person attendance in Levine 307 and virtual attendance on Zoom. ABSTRACT This talk describes investigations into the nature of robot–environment interaction and "niche fit" through the lens of state (or memory) minimization. The idea is that by limiting what a robot can store, much like so-called bottleneck methods, […]

    CBE Seminar: “Creating a New Circular Carbon Economy via Carbon Capture, Utilization and Storage” (Alissa Park, UCLA)

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

    Abstract: To meet the ever-increasing global energy demands while addressing climate change, the development of carbon capture, utilization and storage (CCUS) technologies is one of the critical needs. In particular, there have been significant efforts to develop innovative CO 2 capture materials and CO 2 conversion technologies to create a new circular carbon economy based […]

    MSE Seminar: “Single Metal Site Catalysts for Sustainable and Clean Hydrogen Energy”

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

    Fossil fuels have been overwhelmingly used in many industry sectors in past decades, causing significant CO2 and other pollutant emissions, low efficiency, and nonsustainability. Clean and efficient energy storage and conversion via electrochemical reactions associated with hydrogen, oxygen, and water have attracted substantial attention for energy and environmental sustainability. Among compelling energy technologies, hydrogen proton […]
