Research Interests

As a computational astrophysicist, I apply large-scale numerical simulations on parallel computers to the solution of challenging problems in astrophysics and cosmology. My research interests currently include the evolution of galaxies and clusters of galaxiesbinary stars, and supernovae. I also work on computer science/applied mathematics topics such as parallel numerical algorithm developmentsimulation code architecture, and grid-enabled cyberinfrastructure for astrophysics.
