    • MEAM/GRASP Seminar: “Geometric Biologically Inspired Robots that Span Industries from Medical to Manufacturing”

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

    The animal kingdom is full of both human and non-human animals worthy of investigation, emulation and re-creation. As such, my research group has created a comprehensive research program focusing on biologically-inspired robots, and has applied them to search and rescue, minimally invasive surgery, and manufacturing. These robots inspire great scientific challenges in mechanism design, control, […]

    ESE Seminar: “Hardware Acceleration in the World of Emerging Applications”

    /
    Berger Auditorium (Room 13), Skirkanich Hall 210 South 33rd Street, Philadelphia, PA, United States

    Abstract: Semiconductor technology scaling coming to a screeching halt, coupled with the explosion of data in almost every facet of our lives, makes processing large volumes of data efficiently a critical problem to solve. In this talk, I will highlight three main challenges in designing accelerators and demonstrate that domain-specific hardware acceleration and specialization can […]

    MEAM Seminar: “Elastomeric Materials for Autonomic Force Transmission, Optoelectric Sensing, and 3D Printing Soft Robots”

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

    This talk will present multidisciplinary work from material composites and robotics. We have created new types of actuators, sensors, displays, and additive manufacturing techniques for soft robots and haptic interfaces. For example, we now use stretchable optical waveguides as sensors for high accuracy, repeatability, and material compatibility with soft actuators. For displaying information, we have […]

    CIS Seminar: “Made to Order: Verifying Correctness and Security of Hardware through Event Orderings”

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

    Correctness and security problems in modern computer systems can result from problematic hardware event orderings and interleavings during an application’s execution. Since hardware designs are complex and since a single user-facing instruction can exhibit a variety of different hardware execution sequences, analyzing and verifying systems for correct event orderings is challenging. My work addresses these […]

    SEAS Lecturers’ Seminar on Teaching and Learning: “The Process of Becoming: Identity in Engineering Education”

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

    Identity is an enduring and continuous sense of who one is and is often thought of as the answer to the questions, “Who am I, Who can I be, and Where do I belong?” Research shows that developing a robust engineering identity is important for academic and personal development, integration into engineering, and retention within […]

    • MEAM Seminar: “Hairy Hydrodynamics”

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

    Flexible slender structures in flow are everywhere. While a great deal is known about individual flexible fibers interacting with fluids, considerably less work has been done on fiber ensembles — such as fur or hair — in flow. These hairy surfaces are abundant in nature and perform multiple functions from thermal regulation to water harvesting […]

    ESE Seminar: “Liquid Silicon: A New Computing Paradigm Enabled by Monolithic 3D Cross-Point Memory”

    /
    Room 337, Towne Building 220 South 33rd Street, Philadelphia, PA, United States

    Almost every subfield of electrical engineering and computer science are undergoing disruptive times. With Moore's Law coming to an end, an expanded roadmap for semiconductors beyond traditional CMOS scaling becomes unclear. At the other end, traditional application software development is being replaced by emerging machine learning techniques whose success will, in turn, rely on the […]

    ESE Seminar: “Local Geometric Spectral Data Analysis”

    /
    Berger Auditorium (Room 13), Skirkanich Hall 210 South 33rd Street, Philadelphia, PA, United States

    Modern technological developments have enabled the acquisition and storage of increasingly large-scale, high-resolution, and high-dimensional data in many fields. Yet in domains such as biomedical data, the complexity of these datasets and the unavailability of ground truth pose significant challenges for data analysis and modeling. In this talk, I present new unsupervised geometric approaches for […]

    MEAM Seminar: “Fluid Mechanics and Turbulence in Extended Wind Farms”

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

    In this presentation we discuss several properties of the flow structure and turbulence in the wind turbine array boundary layer (WTABL). This particular type of shear flow develops when the atmospheric boundary layer interacts with an array of large wind turbines. Based on such understanding, we aim to develop reduced order, analytically tractable models. These […]
