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, the Penn Institute for Computational Science (PICS), and the Graduate Group in Applied Mathematics and Computational Science (AMCS). My research interests include physics-based simulation for computer graphics and computational science and engineering.

Current research focus: physics-based animation, multicore and GPU scientific computing, computational solid and fluid mechanics.

Postdoc opening: HPC-oriented scalable multiphysics (particle-in-cell and material point method) simulation on next-gen architectures.

MPM papers in Computer Graphics: Up to November 2019.

MPM courses (SIGGRAPH 2016 and 2019) http://mpm.graphics, http://www.materialpointmethod.com.

News

  • We had 4 physics-based simulation papers and 1 course on high performance simulation presented at SIGGRAPH 2019.
  • Our work on tearing apart virtual food at [VICE].
  • I co-chaired the Penn PICS 2018 conference.
  • Our work on MPM snow simulation is published in Nature Communications! [Penn Today], and it is one of the top 50 most read (out of 5000) articles in Nature Communication 2018's Earth and planetary sciences!
