Research Abstract
I am interested in the long-time behavior of solutions to dissipative Partial Differential Equations, such as the Navier-Stokes equations, and in designing numerical method for integrating them. Also, I am interested in identifying the degrees of freedom that mentor this finite dimensional long-time behavior in order to be able to control these solutions.
