    • MEAM Seminar: “Control of Jump Stochastic Systems by Learning Recurrent Spatiotemporal Patterns”

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

    Efficient learning for stochastic control and estimation remains a topic of high interest in a variety of disciplines and there are well-known advantages and disadvantages to both model-free and model-based learning. On one hand, it is becoming increasingly more feasible to rely entirely on model-free/data-driven methods for controlling complex stochastic systems, but a well-known issue […]

    MSE Seminar: “Fundamental Understanding of Mechanical Properties and Deformation Mechanisms of Emerging Complex Alloys Serving under Extreme Conditions” (Lawrence Berkeley National Laboratory)

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

    The development of stronger and tougher materials serving under extreme conditions is a long-term goal of materials research that has been made even more urgent recently by our quests for space exploration and energy sustainability. Recently, the advent of alloys with increased complexity, e.g., multi-principal element alloys (MPEAs), additively manufactured (AM) alloys, and alloys with […]

    ESE Spring Seminar – “Scalable Data-Driven Decision-Making for Smart Autonomous Power and Energy Systems”

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

    Rapidly growing renewable generations and peak loads pose a serious threat to the security and reliability of modern power and energy systems. A critical question is "how to accommodate a high penetration of renewable generation and deep electrification?". This talk focuses on two key challenges, i.e., unknown information and the scalability issue of coordinating large-scale […]

    CNT/PHT Seminar: “The Future of Brain Interfacing” (Philip Sabes, Neuralink, UCSF)

    /
    Rubenstein Audtorium, Smilow Center for Translational Research

    "The Future of Brain Interfacing" Brain interfacing holds immense promise, both for restoring lost sensory, motor or cognitive function and for the treatment of neurological and neuropsychiatric disorders. The promise is driving a great deal of interest in brain interfacing technologies -- from researchers, industry, investors, and the public -- yet the clinical impact of […]

    BE Seminar: “Building Tissues: Engineering Complexity Through Biomaterial Design” (Brendan Harley, University of Illinois)

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

    Advances in the fields of tissue engineering and regenerative medicine require biomaterials that instruct, rather than simply permit, a desired cellular response. A major challenge to progress in our field is the complex organization of the tissues in our bodies, which are hierarchical, vary in space and time, and can differ person-to person. Prof. Harley’s […]

    CIS Seminar: ” Foundations of Responsible Machine Learning”

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

    Algorithms make predictions about people constantly.  The spread of such prediction systems has raised concerns that machine learning algorithms may exhibit problematic behavior, especially against individuals from marginalized groups.  This talk will provide an overview of my research building a theory of "responsible" machine learning.  I will highlight a notion of fairness in prediction, called […]

    Spring 2023 GRASP on Robotics: Jeannette Bohg, Stanford University, “Scaling Robot Learning for Long-Horizon Manipulation Tasks with Language, Logic and Youtube”

    /
    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 My long-term research goal is enable real robots to manipulate any kind of object such that they can perform many different tasks in a wide variety of application […]

    MEAM Seminar: “Strategies for Approaching One Hundred Percent Dense Lithium-Ion Battery Cathodes”

    /
    Towne 309 220 S. 33rd Street, Philadelphia, PA, United States

    Creating thick electrodes with low porosity can dramatically increase the available energy in a single cell and decrease the number of electrode stacks needed in a full battery, which results in higher energy, lower cost, and easier to manufacture batteries. However, existing electrode architectures cannot simultaneously achieve thick electrodes with high active material volume fractions […]

    ESE Spring Seminar – “Architecting High Performance Silicon Systems for Accurate and Efficient On-Chip Deep Learning”

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

    The unabated pursuit for omniscient and omnipotent AI is levying hefty latency, memory, and energy taxes at all computing scales. At the same time, the end of Dennard scaling is sunsetting traditional performance gains commonly attained with reduction in transistor feature size. Faced with these challenges, my research is building a heterogeneity of solutions co-optimized […]

    MEAM Seminar: “Bioinspired Microrobotic Systems for Interfacing with Cells and Tissues”

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

    Control over the microscopic world, at the scale of the smallest organisms, depends on the development of robots and machines that can operate at micro-nanoscales. However, fundamental limitations in the efficient miniaturization of macro-scale robotic technologies require bioinspired/hybrid approaches for actuation, sensing, and control of microrobots. Recent advances in materials, fabrication and actuation technologies have […]

    MSE Seminar: “Textile Materials for Soft Wearable Robotics” (Stanford University)

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

    Wearable robots and devices—garments with embedded elements that actuate to change shape or apply forces to the wearer, typically based on signals from integrated sensors—offer promise for assistive and augmentative applications including rehabilitative gloves, haptic devices, and dynamically thermoregulating clothing. Early iterations of wearables from the 50s and 60s primarily took the form of rigid […]
