    • CBE Seminar: “Revealing the Unknown Dynamics of High-Energy Density Lithium-Metal Batteries”

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

    Abstract High-energy density batteries will play a remarkable role in hurdling global climate change. My research focuses on the fundamental understandings of their electrochemical reaction mechanisms and the design of materials, protocols, and characterization tools to enable their safe operations over long-term use. First, I will discuss about the previously overlooked dynamics of detached lithium […]

    MSE Seminar: “Engineering Organoid Models for Understanding Human Neurodevelopment and neurological disorders”

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

    Human Induced pluripotent stem cells (hiPSCs) has the potential to generate all cell types of a human body under 2D culture conditions or form organ like structures-organoids, under 3D culture conditions. Brain organoid cultures from human iPSCs have been recently developed to recapitulate the cellular composition and the cytoarchitecture of the developing brain. These hiPSC […]

    ESE Spring Colloquium – “The One Learning Algorithm Hypothesis– Towards Universal Machine Learning Models and Architectures”

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

    We revisit the “One Learning Algorithm Hypothesis” of Andrew Ng (Google Brain) according to which the brain of higher-level animals and of humans processes and perceives sensory data (vision, sound, haptics) with the same abstract algorithmic architecture. We develop models, based on our earlier work on automatic target recognition with radar and other sensors, face […]

    BE Seminar: “Orchestrating Cellular Regeneration at Organ Scale” (Yvon Woappi)

    /

    Large scale tissue damage, such as organ failure and burn injury, is a leading cause of morbidity and death. However, the mechanisms underlying full regeneration of organs remain poorly understood. As the largest organ system in the body, the integumentary system is a composite tissue assembly evolutionarily adapted for healing. Consequently, its complex physiology requires […]

    CIS Seminar: “Social Reinforcement Learning”

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

    this talk will also be on zoom: https://upenn.zoom.us/j/92928358554?pwd=MWdDU0lJRmE3U0hDWUdmU284UmNGZz09
    Meeting ID: 929 2835 8554

    GRASP on Robotics: Andreas Malikopoulos, University of Delaware, “Separation of Learning and Control for Cyber-Physical Systems”

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

    *This will be a VIRTUAL Event with attendance via Zoom Webinar here.  Cyber-physical systems (CPS), in most instances, represent systems of subsystems with an informationally decentralized structure. To derive optimal control strategies for such systems, we typically assume an ideal model, e.g., controlled transition kernel. Such model-based control approaches cannot effectively facilitate optimal solutions with […]

    • MEAM Seminar: “Mechanistic Insights into Crystalline Interfaces via Thermal Fluctuations”

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

    Interfaces such as grain boundaries are ubiquitous in crystalline materials and have provided a fertile area of research over decades. Their importance stems from the numerous critical phenomena associated with them, such as grain boundary sliding, migration, and interaction with other defects that govern the mechanical properties of materials. Although these crystalline interfaces exhibit small […]

    Spring 2022 GRASP SFI: Anthony Bisulco, University of Pennsylvania, “A Tutorial on Neuromorphic Vision for High-Speed Perception”

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

    This seminar will be held in person in Levine 307 as well as via Zoom. Mobile robot systems operate in dynamic environments, such as forests, caves, or roadways, where they must perceive and react to incoming stimuli. Each of these environments presents unique challenges such as perception in low-light conditions, high-speed understanding of objects, and […]

    CBE Seminar: “From Trash to Treasure: Advancing the Heterogeneous Catalytic Deconstruction and Upcycling of Waste Polyolefins”

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

    Abstract The rapid global consumption of single-use plastics has caused an unsustainable accumulation of plastic waste in landfills and the environment. Unfortunately, current mechanical recycling methods are expensive and produce lower-quality products. New strategies in targeted chemical upcycling of waste plastics offer unique opportunities for selective depolymerization of polyolefins to higher value chemicals under milder […]

    MSE Seminar: “Thermodynamic contributions to glass fragility”

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

    Liquid fragility characterizes the rate of drop off in viscosity of a glass-forming liquid as its temperature increases above the glass transition. This property is fundamental to glass physics and of critical importance for engineering applications, yet its origin is unclear. Competing theories suggest that vibrational properties may play a role in fragility by contributing […]
