My research is focused on numerical relativity and gravitational wave modeling using data-driven methods. 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 my group and collaborators are working on, or have worked on in the past.
