    • 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 […]

    PSOC@Penn: Celeste Nelson

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

    Room: Towne 225/Raisler Lounge For zoom link, contact manu@seas.upenn.edu.

    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 […]

    CBE Seminar: “Spatial and Dynamical Control in Metabolic Engineering Using Organelle Engineering and Optogenetics”

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

    Abstract Metabolic engineering aims to rewire cellular metabolism, typically of microorganisms, to produce fuels, chemicals, pharmaceuticals, and other valuable products from renewable resources. However, it is often challenging to achieve the titers, yields, and productivities required for commercial viability. Spatial and dynamical control of engineered metabolic pathways can greatly improve their efficiency to address this […]

    MSE Seminar: “Topological Physics: from Photons to Electrons”

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

    There are many intriguing physical phenomena that are associated with topological features --- global properties that are not discernible locally. The best-known examples are quantum Hall effects in electronic systems, where insensitivity to local properties manifests itself as conductance through edge states which are insensitive to defects and disorder. In this talk, Dr. Hafezi will […]

    BE Seminar: “Phage and Robotics-Assisted Biomolecular Evolution” (Emma Chory)

    /
    Moore 216 200 S. 33rd Street, Philadelphia, PA, United States

    This seminar will be held live and broadcast on zoom - check email for link or contact ksas@seas.upenn.edu. Evolution occurs when selective pressures from the environment shape inherited variation over time. Within the laboratory, evolution is commonly used to engineer proteins and RNA, but experimental constraints have limited our ability to reproducibly and reliably explore […]
