    • ESE PhD Thesis Defense: “Affordances and Control of a Spine Morphology for Robotic Quadrupedal Locomotion”

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

    Abstract: How does a robot’s body affect what it can do? This talk explores this question with respect to a morphology common to biology but rare in robotics: the presence of a bendable back. Using the Canid and Inu quadrupedal robots, I describe and quantify several advantages afforded by this morphological design choice for legged […]

    MEAM Doctoral Dissertation Defense: “Estimation, Mapping and Navigation with Micro Aerial Vehicles for Infrastructure Inspection”

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

    Multi-rotor Micro Aerial Vehicles (MAV) have become popular robotic platforms in the last decade due to their manufacturability, agility and diverse payload options. Amongst the most promising applications areas of MAVs are inspection, air delivery, surveillance, search and rescue, real estate, entertainment and photography to name a few. While GPS offers an easy solution for […]

    • BE Seminar: “High-throughput T cell repertoire profiling enabled systems immunology and immune engineering”

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

    T cells are important to the initiation, prevention, and cure of many diseases. For example, various T cells based cancer immunotherapies have been quite effective in treating several types of cancers. However, a significant fraction of patients do not respond. A comprehensive understanding of the complexity of the T cells repertoire in health and diseases […]

    REACT@Penn 2020: Global Pathways to enable Innovative Materials Solutions for Urban Challenges

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

    How can science and technology help cities solve their problems?  Are there common urban air, water and energy challenges for science to tackle? 10:00 am Urban Challenges with (potential) Materials Solutions Model cities of Grenoble, France, Philadelphia, USA and Seoul, Korea 1:30 pm Adoption and Adaptation of New Technologies for Urban Challenges Joshua Sperling, National […]

    MEAM Seminar: “Confined Curved Shells and their Elaborate Conformations”

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

    Curved shells, when confined, can deform to a broad assortment of large scale shapes and smaller scale wrinkling and folding patterns quite unlike what produced by their flat counterparts. The intrinsic, natural curvature of shells is the central element that allows for this rich and very interesting morphological landscape, but it is also the source […]

    MSE Materials in Practice Seminar: “So You’re an Engineer…Now What?”

    /
    LRSM Reading Room 3231 Walnut St., Philadelphia, PA, United States

    Materials in Practice is a seminar series where technologists who are using materials science to shape the world we live in share their secret to doing this. We hope that anyone who wants to apply the research they are doing to solve real world problems will be able to attend this Seminar Series.

    MSE Grace Hopper Lecture: “Artificial Intelligence for Generating Materials Science Knowledge”

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

    The process of scientific inquiry involves observing a signal (data) and interpreting it to generate information (knowledge). For example, in electron microscopy the signal may be a diffraction pattern from which information on crystal orientation may be deduced by applying diffraction theory. Science advances both through improvements in gathering data and in techniques for extracting […]

    MEAM Seminar: “Plate Mechanical Metamaterials and their Applications”

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

    Recently, we introduced the concept of plate mechanical metamaterials—cellular plates with carefully controlled periodic geometry and unique mechanical properties—as well as its initial realization in the form of freestanding corrugated plates made out of an ultrathin film. We used atomic layer deposition (ALD) and microfabrication techniques to make robust plates out of a single continuous […]

    CIS Seminar: “Networked Systems in the Era of Programmable Dataplanes”

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

    Abstract:  Emerging networking architectures are allowing for flexible and reconfigurable packet processing at line rate both on the switch and the NIC. Despite their promising new functionality, programmable switches and NICs are not all-powerful; they have limited state, support limited types of operations, and limit per-packet computation to operate at line rate. In this talk, I […]

    CBE Seminar: “Collaboration and Competition Between Active Sheets for Self-Propelled Particles”

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

    Abstract: Biological species routinely collaborate for their mutual benefit or compete for available resources, thereby displaying dynamic behavior that is challenging to replicate in synthetic systems. Here, we use computational modeling to design microscopic, chemically active sheets and self-propelled particles encompassing the appropriate synergistic interactions to exhibit bio-inspired “feeding”, “fleeing” and “fighting”. This design couples […]
