I am a computational/theoretical astrophysicist in TAPIR, which is part of the Walter Burke Institute for Theoretical Physics at Caltech, working at the interface of numerical relativity, nuclear/neutrino astrophysics, and gravitational-wave physics. My current primary research interest is to find ways to blow up massive stars, that is, make core-collapse supernovae and gamma-ray bursts and their compact remnants, black holes and neutron stars. This work is carried out as part of the Simulating eXtreme Spacetimes (SXS) collaboration and we also work closely with the Einstein Toolkit team. Another line of my research is concerned with the observation and interpretation of gravitational waves using the LIGO interferometers and I am a member of the LIGO Scientific Collaboration.
