I am an Assistant Adjunct Professor at UCLA Department of Mathematics. I was a postdoc in the SIG Lab at University of Pennsylvania working with Prof. Chenfanfu Jiang after completing my Ph.D. in the same group. My research interests include numerical optimization and differentiable simulation for computer graphics, computational physics, and robotics. I am a winner of the 2021 ACM SIGGRAPH Outstanding Doctoral Dissertation Award, the 2021 Symposium of Computer Animation (SCA) Doctoral Dissertation Award, and the 2020 Adobe Research Fellowship,

My Ph.D. dissertation features the invention of the Incremental Potential Contact (IPC) method that enables Robust and Accurate Simulation of Elastodynamics and Contact, which leads to a series of follow-up works in both academia and industry. I had 4 wonderful internships at Adobe Research, working with Dr. Danny Kaufman, Dr. Timothy Langlois, and Dr. Vladimir (Vova) Kim on elastodynamics simulation (C-IPC, IPC, DOT) and surface cutting and parameterization (OptCuts). During my M.Sc., I worked with Prof. Alla Sheffer on garment design optimization (FoldSketch), OptCuts, etc. I was also very lucky to collaborate with Dr. Xinxin Zhang and Prof. Robert Bridson on smoke simulation.
