I work in numerical simulations
of strongly gravitating systems. Compact object binaries (systems with
two black holes or neutron stars), can only be accurately described in
the framework of
the Theory of General Relativity. Unfortunately, modeling such systems
requires large amounts of computational resources. The simulations are
performed with the most advanced supercomputers I can get my hands on.
I currently use Beowulf clusters at NCSA Teragrid, SDSC, PSC, etc.
