Projects

I do research in numerical relativity, with occasional forays into parallel computing projects in other fields. Here I list projects in which I am either actively or have been recently involved. Descriptions of these projects will be added as time permits.
  • The effects of magnetic fields on the dynamical bar-mode instability in rotating stars
  • Studies of distorted black holes
  • Studies of primordial black holes
  • A parallel implementation of a chemical reactor simulation using Cactus
