MEAM Seminar: “Leveraging Unsteady Flows for Enhanced Performance in Wind-Energy Systems”

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

Wind energy is poised to play a considerable role in the global transition to clean-energy technologies within the next few decades. Modern wind turbines, like aircraft and other aerodynamic structures, are typically designed with the assumption that the flows they encounter will be uniform and steady. However, atmospheric flows are highly unsteady, and systems operating […]

ESE Spring Seminar – “In pursuit of entanglement: XXZ interactions for spin-squeezing in atomic and solid-state spin ensembles”

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

Controlling many-body entanglement promises to yield both fundamental insights and practical advances. In particular, generating squeezed states for entanglement-enhanced metrology is an important near-term application of quantum systems. In past work, squeezing has been achieved in a clean, controlled setting using all-to-all Ising interactions between ultracold atoms in an optical cavity. By contrast, optically-addressable spin […]

CIS Seminar: “Secure Computation with Minimal Interaction”

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

In the current digital and decentralized world, there is an imminent need for technologies that can provide a fast approach to compute on private data while guaranteeing secrecy. Secure Multiparty Computation (MPC) is one such cryptographic technology that provides an efficient approach to compute on private data. At a high level, MPC is a distributed […]

Launched in May 2021, the Future Leaders in Mechanobiology is a monthly seminar series featuring up-and-coming leaders in mechanobiology–PhD students and postdocs from a wide range of fields, backgrounds, and institutions. By providing an international stage to share one’s work and opportunities to interact with researchers at all career stages, we aim to create an inclusive and […]

Spring 2023 GRASP SFI: Jinwei Ye, George Mason University, “Seeing 3D with Polarized Light”

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

This is a hybrid event with in-person attendance in Levine 307 and virtual attendance via Zoom. This week's presenter will be in-person as well. ABSTRACT Polarization is a fundamental property of light that describes the direction in which the electric field of light oscillates. Polarization, as an intrinsic property of light, provides an extra dimension […]

CBE Seminar Series: “Developing Strategies for Polymer Redesign and Recycling Using Reaction Pathway Analysis” (Linda Broadbelt, Northwestern University)

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

Abstract: The current lack of sustainability of and the limited portfolio of recycling processes for synthetic polymers have posed serious threats to the environment. Using reaction pathway analysis, we are pursuing a portfolio of strategies for redesign and recycling of polymers for sustainability. Pyrolysis is a promising method for resource recovery from plastic waste that […]

MEAM Seminar: “Mechanics for Energy Sustainability: From Fatigue of 2D Materials to Dendrites in Solid-state Batteries”

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

Achieving energy sustainability requires efforts from not only sourcing clean energy, but also storing and dispatching energy whenever and wherever needed, as well as being energy-efficient whenever possible. Two-dimensional (2D) materials hold great promises as mechanical reinforcement in high strength-to-weight ratio structural materials and as next-generation energy-efficient electronic materials, both of which contribute to less […]

MSE Seminar: “Design of Stable Nanocrystalline Alloys: Thermodynamics, Computation, and Data Science” (Massachusetts Institute of Technology)

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

Over the last three decades, nanocrystalline alloys (polycrystals with grain sizes of less than 100 nm) have been shown to exhibit superior material properties, such as enhanced specific strength, hardness, wear resistance, radiation resistance, and magnetic properties. However, such structures are inherently thermodynamically unstable; a nanocrystalline configuration comes with a large volume fraction of high-energy […]

CIS Seminar: “Cryptography, Security, and Law”

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

My research focuses on the security, privacy, and transparency of technologies in societal and legal context. My talk will focus on three of my recent works in this space, relating to (1) preventing exploitation of stolen email data, (2) enhancing accountability in electronic surveillance, and (3) legal risks faced by security researchers.
