Research Interests

I am interested in developing fast computational methods for the prediction of the behavior of physical systems. These predictions can be used for analysis, design optimization, uncertainty quantification and control. I have focused in the past on the simulation of fluid-structure interaction, turbulent flows, nonlinear structural mechanics, signal propagation in neurons and circuit simulation.

Below is a list of key topics I have focused on in the last few years:
