My research is in the broad area of nonlinear dynamics and incorporates both computation and analysis. Much of my work concerns fluid dynamics, but I also study simpler ordinary and partial differential equations. Recently I have been developing ways to use the convex optimization technique of semidefinite programming to study dynamical systems, for instance to estimate time averages and other properties of attractors.
