Assistant Professor  

I joined the faculty of Computer Science Department at Columbia University right after I received my PhD from Cornell University. Now I am a member of Columbia's Computer Graphics Group (C2G2) in Columbia Vision and Graphics Center (CVGC). I work in applied computer science, focusing on computer graphics, scientific computing and robotics.


Research Statement
One focus of my research concerns realistic synthesis of virtual sounds for computer graphics applications. We are developing practical algorithms that automatically generate virtual sounds synchronized with animated dynamics. The goal is to create realistic virtual environments that are both visible and audible for entertainment, training, design or other applications.

More broadly, I am interested in realistic simulations that involve really complex dynamics. Such high-fidelity simulations usually require either complex physical models or prohibitively expensive computation. We draw ideas from physical insights, mathematical approximations and perceptual studies, developing new approaches to enable practical high-fidelity simulations for computer graphics and robotics applications.
