Kick-off LGBTQ+ History Month and warm-up for National Coming Out Day with a bang! Come to our festival featuring queer dance lessons (no experience needed), progressive pride flags galore, and of course yummy food (gluten-free and vegan options available; more TBA. All are welcome.
Periodic media and resonant, acoustic/elastic metamaterials possess extraordinary frequency band gaps where no waves may propagate. In this dissertation, we leverage numerical simulations to gain insight into practical ways to effectively measure and characterize the behavior of these materials from experimental observables and also explore physical mechanisms to optimize their performance, particularly in the context […]

Soft robotics, energy harvesting, large-deformation sensing and actuation, are just some of the applications that can be enabled by soft dielectrics that demonstrate substantive electromechanical coupling. Imagine now also a material that will produce electricity and deform substantively via a contactless, wireless magnetic signal. Unfortunately, truly soft, naturally occurring piezoelectric or magnetoelectric materials essentially do […]
Heterogeneous materials are commonly found in nature (e.g. soil, rock, blood) and engineering applications (e.g. paints, lubricants, sintered materials). Understanding the microstructure-properties relations is crucial to predicting how these materials fail and behave during processing. In this thesis, we develop semi-analytical homogenization estimates for the macroscopic properties and field statistics of viscoplastic composites. A generalization […]
Quantum processors of today are already capable of surpassing classical supercomputers on certain specialized tasks . A current milestone for the quantum information science community is the fulfilment of quantum computational advantage on a practical problem of interest. The beginning of this talk will outline our technical progress on realizing various high-fidelity quantum gates on […]
Yansong Gao Title: "A Free-Energy Principle for Representation Learning" Keshav Patil Title: "Altered protein dynamics delineates the oncogenic potential of various kinase mutations" On Wednesday, October 6 at 12:00, PICS will host a virtual student seminar featuring Yansong Gao, a 4th year PhD in the Chaudhari group; and Keshav Patil, 4th year PhD in the […]
Abstract Electrolytes are critical enabling components for Li-ion batteries to safely operate within a wide temperature range, under extreme fast charging, and under intense abuse conditions without sacrificing energy density and cycle life. Current electrolytes cannot satisfy these requirements. We developed advanced all-fluorinated electrolytes, water-in-sale (WIS) electrolytes and solid-state electrolytes aiming to simultaneously enhance cell […]
Today in the U.S., we deal with the severe, wide ranging effects of climate change from the West to East Coast in the form of heat waves, drought, wildfires, and flooding. To end these disasters, we need to drastically change the way we produce and use energy. For example, in 2020, over 72 % of […]
The past two decades have witnessed incredible advances towards the design of autonomous systems. This talk will discuss the role of motion planning in yielding solutions for an agent that is able to execute a variety of tasks in a variety of settings. Problem decomposition has been and remains a difficult task, and motion planning […]
