I joined the faculty of Computer Science Department
at Columbia University
right after I received my PhD from
Now I am co-directing Columbia's Computer Graphics Group
Columbia Vision and Graphics Center
I work in applied computer science, focusing on computer graphics, scientific computing and robotics.
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
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, computational design and robotics applications.
