About

I am a Research Scientist in 3D Deep Learning at NVIDIA (Toronto AI Lab), based in Santa Clara, CA, USA. Previously, I received my Ph.D. in Computer Science from Stanford University, advised by Prof. C. Karen Liu, and my M.S. in Electrical and Computer Engineering from Georgia Tech. Prior to attending graduate school, I got my Bachelor's degree from Shanghai Jiao Tong University, where I was a member of the University of Michigan – Shanghai Jiao Tong University Joint Institute.

As a character animation researcher, I explore new methods that combine machine learning and simulation-based techniques to build AI-driven Digital Humans, and to enable humanoid robots with naturalistic movements through physics simulation. Besides motion generation, I have worked on human motion inference using wearable sensors, such as smart glasses, and on developing next-generation human simulations for biomechanics and healthcare applications.

Miscellaneous and Resources

I am fan of classical music. Here is an introductory list where I picked some of the most well-known pieces - those I feel being accessible to people who are interested in classical music, but do not know where to start. My favorite musician is Tchaikovsky.

I am also interested in psychology. Psychology and Life (Chinese Edition Here) is one of the best introductory books. I found reasoning about Nature vs Nurture a very good way to combat unconscious biases. I also enjoyed a lot watching Dr. Tal Ben-Shahar's open course on Positive Psychology (Chinese Translations Here). Finally, a wonderful (full of humor) introductory course at Yale.

My favorite books are Gone with the Wind and The Three-Body Problem.

An small visual catalog I made of some of the over 400 kinds of trees on Stanford campus.
