    • ASSET Seminar: Machine Learning: A Data-Centric Perspective, Aleksander Madry (Massachusetts Institute of Technology)

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

    ABSTRACT: The training data that modern machine learning models ingest has a major impact on these models’ performance (as well as failures). Yet, this impact tends to be neither fully appreciated nor understood at a fine-grained enough level. In this talk, we will discuss some of the key ways in which training data influences not […]

    Spring 2023 GRASP SFI: Wenzhong Yan, UCLA, “Mechanical Intelligence for Compliant Robots”

    /
    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. This week's presenter will be in-person as well. ABSTRACT Biological systems with deformable bodies exhibit remarkable abilities. However, compliant/soft robots still can not match the capabilities of their biological analogs in terms of adaptability, physical robustness, and autonomy partially […]

    Seminar: Accelerating Clean Energy Technologies: Pathways to Commercial Liftoff

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

    Wednesday, April 12, 2023 5:00 PM Wu and Chen Auditorium Anna Siefken Department of Energy Office of Technology Transitions President Biden’s Bipartisan Infrastructure Law and Inflation Reduction Act provided DOE billions of dollars to invest in and support large-scale demonstration and deployment of clean energy technologies over the next decade. These historic investments are intended […]

    MSE Seminar: “‘Low Dimensional’ Rare-Earth-Free Permanent Magnetic Materials” (University of California, Riverside)

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

    Critical elements such as rare-earth (RE) metals that are subject to supply risks and are incorporated in critical materials, play a central role in the function of these materials. They dictate the properties that control the function of critical materials, including both molecules and materials, used in a broad range of technologically important and energy […]

    BE Doctoral Dissertation Defense: “Generation of Chimeric Antigen Receptor Macrophages to Target Pathogenic Protein Aggregates in Alzheimer’s Disease” (Matias Porras Paniagua)

    /
    Smilow Center for Translational Research in SCTR 11-146AB

    The Department of Bioengineering at the University of Pennsylvania and Drs. Saar Gill & Frederick Bennett are pleased to announce the Doctoral Dissertation Defense of Matias Porras Paniagua. Title: Generation of Chimeric Antigen Receptor Macrophages to Target Pathogenic Protein Aggregates in Alzheimer's Disease Date: April 13, 2023 Time: 3:15pm Location: Smillow Center for Translational Medicine: SCTR 11-146AB […]

    BE Seminar: “MAPing Principles and Applications to Endogenous Repair” (Tatiana Segura, Duke University)

    /
    Glandt Forum, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

    This seminar will be held in person in Glandt Forum; snacks will be served. "MAPing Principles and Applications to Endogenous Repair" Microporous annealed particle (MAP) scaffolds are materials composed of hydrogel microparticle (HMP) building blocks. Thus, rather than use polymers as the building block that form the hydrogel, we use particles. This makes MAP scaffolds […]

    Spring 2023 GRASP on Robotics: Luca Carlone, MIT, “Next-Generation Robot Perception: Hierarchical Representations, Certifiable Algorithms, and Self-Supervised Learning”

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

    This is a hybrid event with in-person attendance in Wu and Chen and virtual attendance via Zoom. This week's presenter will be in-person as well.    ABSTRACT Spatial perception —the robot’s ability to sense and understand the surrounding environment— is a key enabler for robot navigation, manipulation, and human-robot interaction. Recent advances in perception algorithms […]

    PICS Colloquium: “Bridging scales in aerosol modeling with particle-resolved simulations”

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

    The aerosol lifecycle consists of processes that act on the micro-scale, yet the aerosols’ climate impacts are perceived on regional or global scales. Capturing this multiscale nature of the atmospheric aerosol poses considerable challenges for aerosol models since computational constraints limit the detail of aerosol representation, yet these details matter in determining large-scale aerosol impacts. […]

    ESE PhD Thesis Defense: “Leveraging Models to Improve Data Efficiency: Navigation, Reinforcement Learning, and Lie Group Convolutions”

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

    Consider a system which takes data as an input, processes the data with a model, and outputs a decision for a particular objective. We call the measure of the amount of data used to complete the objective with some performance metric as data efficiency.  Across many domains, it is advantageous to reduce the amount of […]

    MEAM Seminar: “Nano and Polymers and Mechanics and Data”

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

    For polymer composites, nanocomposites and polymer thin film systems, the local properties of polymers can be altered by the chemical and physical interactions with substrates and embedded particles over a length scales exceeding 100nm. The mechanisms and impact of confined polymers remains still an active area of research and debate. Here we will review methods […]
