Research

My research is focused on numerical relativity and gravitational wave modeling. In general, I am interested in relativistic astrophysics, particularly involving compact objects such as black holes and neutron stars. With no promises of maintaining it up to date, here I will try and summarize the projects I'm working on, or have worked on in the past.

Introduction

For a popular science level introduction, check out my article for Caltech Letters on gravitational waves, numerical relativity, and surrogate models.
