My research brings together numerical methods and computer animation. It is difficult to animate many natural phenomena (at least to the level of photorealistic motion) with traditional keyframe approaches: a powerful alternative is to directly simulate the underlying physics of the phenomena. For example, the motion of a digital actor's clothes can be simulated automatically with a good model for the elastic forces and the frictional contact interactions. Traditional computer animation also can benefit from advanced numerical algorithms in shape modeling and motion processing.

I also am interested in mainstream scientific computing, both adapting the robust and scalable (but not necessarily accurate) algorithms for animation to scientific challenges, and developing basic numerical tools that are usable in a wide range of applications. For example, solving sparse linear systems often takes up most of the CPU time in a simulation, so efficient but also robust (no tuning needed) linear solvers are required.
