    • MEAM Ph.D. Thesis Defense: “Coupling Hard and Soft Interfaces to Realize Actuators and Energy Sources that Bring Robots Towards Animal Mobility”

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

    Mobile robots have shown significant advancements in agility, intelligence, and efficiency over the past few decades. However, their endurance and overall performance remain limited by the onboard power supplies. Current power sources typically restrict mobile robots to areas close to the electrical grid and necessitate heavier batteries for extended range. Energy refueling could be significantly […]

    Tedori-Callinan Distinguished Lecture: “Novel Passive and Active Approaches to Fluid Friction Reduction using Polymers & Plastrons”

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

    When a superhydrophobic (SH) textured surface is immersed in water it traps a thin shiny layer of air within the texture that is known as a plastron. Contact line pinning stabilizes this Cassie-Baxter state and the patches of air trapped in the texture can act as shear-free regions that locally lower the frictional dissipation. Recent […]

    ESE Fall Seminar – “Color center photonics in silicon carbide: scalable fabrication, cryogenic experiments, and quantum simulation on NISQ testbeds”

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

    Color center systems are among the leading platforms in the development of quantum communication and quantum sensing hardware due to their desirable spin, optical, and spin-photon properties. Among them, the near infrared emitters in silicon carbide, such as the nitrogen-vacancy center in 4H-SiC, provide fiber-friendly operation in an industrially mature substrate, ideal for scalable deployment […]

    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 […]
