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.
