    • CBE Seminar: “Electrolytes for High Energy Li-ion and Li Metal Batteries”

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

    Abstract Electrolytes are critical enabling components for Li-ion batteries to safely operate within a wide temperature range, under extreme fast charging, and under intense abuse conditions without sacrificing energy density and cycle life. Current electrolytes cannot satisfy these requirements. We developed advanced all-fluorinated electrolytes, water-in-sale (WIS) electrolytes and solid-state electrolytes aiming to simultaneously enhance cell […]

    MSE Seminar: “Metals and Alloys: A Critical Weapon in the Fight against Climate Change”

    /
    Auditorium, LRSM Building 3231 Walnut Street, Philadelphia, PA, United States

    Today in the U.S., we deal with the severe, wide ranging effects of climate change from the West to East Coast in the form of heat waves, drought, wildfires, and flooding. To end these disasters, we need to drastically change the way we produce and use energy. For example, in 2020, over 72 % of […]

    GRASP on Robotics: “Motion Planning for Autonomy: Successes and Challenges Ahead”

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

    The past two decades have witnessed incredible advances towards the design of autonomous systems. This talk will discuss the role of motion planning in yielding solutions for an agent that is able to execute a variety of tasks in a variety of settings. Problem decomposition has been and remains a difficult task, and motion planning […]

    Tedori-Callinan Lecture: “Resist Fatigue by De-concentrating Stress”

    /
    Zoom - Email MEAM for Link peterlit@seas.upenn.edu

    Most materials suffer from a disease: fatigue. Symptoms include degradation of properties and growth of cracks under cyclic stretch. These materials are unfit for applications involving prolonged and cyclic loads. A crack grows in a material because the crack tip concentrates stress. Recently, we have been developing fatigue-resistant materials by de-concentrating stress, through mechanisms at […]

    CIS Seminar:”David V.S. Goliath: the Art of Leaderboarding in the Era of Extreme-Scale Neural Models”

    /

    Scale appears to be the winning recipe in today's leaderboards. And yet, extreme-scale neural models are still brittle to make errors that are often nonsensical and even counterintuitive. In this talk, I will argue for the importance of knowledge, especially commonsense knowledge, and demonstrate how smaller models developed in academia can still have an edge over larger industry-scale models, if powered with knowledge. […]

    CEMB Future Leaders Seminar: “Enhanced matrix stress relaxation promotes cell migration”

    /
    https://upenn.zoom.us/j/96715197752

    Launched in May 2021, the Future Leaders in Mechanobiology is a monthly seminar series featuring up-and-coming leaders in mechanobiology–PhD students and postdocs from a wide range of fields, backgrounds, and institutions. By providing an international stage to share one’s work and opportunities to interact with researchers at all career stages, we aim to create an inclusive and […]

    CBE Seminar: “The Refinery of Today, Tomorrow and the Future: A Separations Perspective”

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

    Abstract The hydrocarbon processing industry is in the midst of a major shift in feedstocks, structure, and products. Aggressive carbon abatement targets and intrinsic efficiency advantages from electric vehicles strongly undercut the advantages of fossil fuels, which are the majority product of this industry. However, the immense value of the existing hydrocarbon infrastructure suggests that […]

    MEAM Seminar: “Computational Mechanics for Landing on Mars”

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

    Current technology for decelerating a spacecraft from the high speed of atmospheric entry to the final stages of landing on Mars is based on low-density supersonic decelerators such as low mass and high packaging efficiency parachute systems. To enable future exploration missions featuring sophisticated robots and safely land heavier spacecraft on Mars, larger than before […]

    ESE Fall Colloquium Seminar – “Distributed Estimation Under Privacy and Communication Constraints”

    /
    Zoom - Meeting ID: 282 221 4402

    Distributed estimation is a central task in modern data science, where datasets are often generated from distributed sources or are too large to be stored on a centralized machine, and communication is subject to bandwidth and privacy limitations. In this talk, we will consider the problem of estimating high-dimensional distributions and their parameters from distributed […]

    Fall 2021 GRASP SFI: “Diversity and Inequality in Social Networks”

    /

    Abstract: Online social networks often mirror inequality in real-world networks, from historical prejudice, economic or social factors. Such disparities are often picked up and amplified by algorithms that leverage social data for the purpose of providing recommendations, diffusing information, or forming groups. In this talk, I discuss an overview of my research involving explanations for algorithmic […]
