Research Summary
I develop geometric and numerical algorithms for computer animation. My latest research couples high resolution embedded surface geometry to low resolution simulations in order to efficiently simulate detailed animations of elastic, plastic, and fluid phenomena. I have additionally designed methods for computing topological changes with mesh-based surface geometry, researched various methods for optimally controlling large physics simulations, and devised schemes for coupling solids and fluids within a simulation.
