Professional Information

I am an assistant professor of Computer and Information Science at the University of Pennsylvania. I joined the CIS department in June 2017. I am a faculty in Penn's SIG Center for Computer Graphics, faculty affiliate at the General Robotics, Automation, Sensing & Perception (GRASP) lab, the Penn Institute for Computational Science (PICS), and the Graduate Group in Applied Mathematics and Computational Science (AMCS). My PhD (2010-2015) and postdoc (2015-2017) experience was under the co-supervision of Demetri Terzopoulos and Joseph Teran. I am a recipient of the UCLA Edward K. Rice Outstanding Doctoral Student Award (2015), NSF CRII award (2018) and NSF CAREER award (2020).

Current research focus: With the central theme being physics-based modeling and simulation, we perform research on numerical optimization, numerical methods for PDEs, continuum mechanics, high performance computing, and machine learning. We target at applications in computer graphics (focusing on animation and VFX), computational physics (solid and fluid mechanics), computer vision (physics-informed scene understanding) and computational design of robots and other smart structures.

Material Point Method (MPM) resources: Papers in graphics (up to 2020/03), SIGGRAPH courses

We presented 6 papers at SIGGRAPH 2020. We published 18 papers on physics-based simulation in SIGGRAPH/SIGGRAPH-Asia/TOG from 2017-2020.

Events: I host the SIG Center for Computer Graphics Colloquium Series with research/industry talks and Penn Institute for Computational Science (PICS) Workshop Series with educational sessions.
