• MEAM Ph.D. Thesis Defense: “Impulse-Induced Nonlinear Dynamics of Flexible Mechanical Metamaterials”

    /
    Room 2C2, David Rittenhouse Laboratory Building 209 S. 33rd Street, Philadelphia, PA, United States

    Mechanical metamaterials are artificially designed structures that exhibit unique properties due to their internal structure rather than their composition, e.g., negative Poisson’s ratio, tunable stiffness, and advanced thermal characteristics. While the static properties of mechanical metamaterials have been widely studied, their nonlinear dynamics remain largely unexplored, which could pave ways for innovative design and optimization […]

    ESE Fall Seminar – “Algorithmic Bias in Computer Vision – Generative Methods Enable the Experimental Approach”

    /
    Wu & Chen Auditorium

    As Artificial Intelligence (AI) finds increasing applications in industry and society. Responsible deployment demands that we measure and correct algorithmic biases vis-a-vis protected attributes such as sex, age and ethnicity. State of the art methods for measuring algorithmic bias rely on test sets that are collected in the wild and are then annotated for the […]

    ASSET Seminar: “Multi-Omic Approaches for Deciphering Cellular Heterogeneity and Plasticity in Cancer”

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

    Abstract: Tumors are complex and heterogeneous systems, which challenge their classification and treatment. The Silverbush lab decodes tumor heterogeneity and plasticity to understand how cancer cells transform to become more aggressive or evade treatment. We particularly examine hard-to-treat cancers with high heterogeneity, focusing on the notorious kings of heterogeneity and aggressiveness: brain cancers. To achieve this […]

    Fall 2024 GRASP SFI: Noémie Jaquier, Karlsruhe Institute of Technology, “The geometric side(s) of Lagrangian dynamics”

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

    This will be a hybrid event with in-person attendance in Levine 307 and virtual attendance on Zoom. This week's speaker will be virtual.  ABSTRACT Lagrangian mechanics provides a powerful framework for modeling the dynamics of physical systems by inferring their motions based on energy conservation. This talk will explore recent advances in applying geometric perspectives, […]

    ESE Guest Seminar – “Coherent Control of Electromagnetic Waves via Tunable Chaotic Cavities”

    /
    Towne 337

    The theory of Coherent Perfect Absorption1 (time-reversed lasing) and Reflectionless Scattering Modes2 has shown that there always exist discrete solutions to scattering of electromagnetic waves in multiple-scattering geometries that achieve perfect transduction or perfect (reflectionless) impedance matching. In general these are transient (complex frequency) solutions, but, typically, with tuning of a one system parameter it […]

    MSE Seminar: “Luminescent Photonic Metamaterials and Devices From THz to Optical Frequencies”

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

    A crucial yet unavailable component in high-performance photonic integrated circuits (ICs) and other chip-scale photonic systems is an on-chip light source that is efficient, functional, IC-compatible, and electronically addressable. In this talk, I will cover several types of on-chip sources, including perovskite microlasers and luminescent hyperbolic metamaterials, topologically protected microlasers on the III-V platform, as […]

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

    *This seminar will be held in-person in Levine 307 as well as virtually via Zoom. This seminar will NOT be recorded. ABSTRACT This talk has two parts. First, I will explain our recent work on making it easier to control 3D soft robots. By extending our prior work on soft robot inverse kinematics (Soft IK) into […]

    Fall 2024 GRASP on Robotics: Damion Shelton, Agility Robotics, “What do we want from our machines?”

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

    This will be a hybrid event with in-person attendance in Wu and Chen and virtual attendance on Zoom. ABSTRACT In 2022 I represented Agility Robotics at the first “Philadelphia Summit” on the weaponization of autonomous robots, co-hosted by the GRASP lab and Boston Dynamics. By late fall, this yielded a joint statement, signed by Agility, […]

    ESE 2024 Jack Keil Wolf Lecture – “Army of Ants: The Power of Working in Concert”

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

    Synchronized operation of a large number of similar entities can generate behavior that cannot be expected from single one. This principle combined with the physical concept of coherence in waves enables creation of programmable 3-dimensional focal points that can be used to enable many applications such as wireless energy transfer at distance on earth and […]
