MEAM Ph.D. Thesis Defense: “Exploring Multimodal Sensing Across the Stack for Robot Manipulation”
Despite substantial progress in robotics, achieving human-like manipulation remains a significant challenge. Existing robotic systems typically leverage human-inspired sensory modalities: vision, touch, and proprioception. However, these modalities are historically studied and integrated in isolation, leading to limited performance in complex real-world tasks that require sensing across multiple modalities for robust generalization. As a result, robots […]
Center for Soft and Living Matter Seminar: “Medium-range Order and Local Structure Fluctuations in Metallic Glass”
Amorphous materials have no long-range order, but there are ordered structures at short-range (2-5 Å), medium-range (5-20 Å), and even longer-length scales. While regular and semiregular polyhedra are often identified as short-range order in amorphous materials, the nature of the medium-range order has remained elusive. Because of the disorder, the dynamics also become far more […]
MEAM Ph.D. Thesis Defense: “Coupling Hard and Soft Interfaces to Realize Actuators and Energy Sources that Bring Robots Towards Animal Mobility”
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 […]

November 12, 2024 -ESE Fall Seminar – “Color center photonics in silicon carbide: scalable fabrication, cryogenic experiments, and quantum simulation on NISQ testbeds”
Tedori-Callinan Distinguished Lecture: “Novel Passive and Active Approaches to Fluid Friction Reduction using Polymers & Plastrons”
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”
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”
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”
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”
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 […]
Introduction to COMSOL Multiphysics® Workshop
We are excited to announce that COMSOL will be coming to the University of Pennsylvania for a free special event. On November 13th at 2pm we will be providing a Introduction to COMSOL Multiphysics® Workshop on campus at 3401 Walnut Street Wing A, Conference Room 534, 5th Floor. At this workshop, you will see the […]
Fall 2024 GRASP SFI: Noémie Jaquier, Karlsruhe Institute of Technology, “The geometric side(s) of Lagrangian dynamics”
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”
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”
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 […]

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