I do research in theoretical and computational astrophysics, mainly
addressing problems associated with very energetic phenomena and their
impact on the universe. My students and I carry out large fluid dynamical
simulations including specially developed routines to follow the microphysics
responsible for the emission we observe from such astronomical objects as
supernova remnants, active galaxies and clusters of galaxies.
Our calculations can be compared directly with observational data
to test basic theories about the origins of these objects.
