Research and Publications

My research focuses on strong-field probes of general relativity, black holes, and gravitational-wave physics. I use theoretical and computational methods, particularly black hole perturbation theory and numerical relativity, to study gravitational collapse, quasinormal modes, ringdown physics and late-time dynamics. More broadly, I am interested in understanding how gravity behaves in extreme regions of spacetime and how gravitational waves, black hole shadows, gravitational lensing, and geodesic motion can be used to test gravity in the strong-field regime.

I have also been fortunate to collaborate with many researchers in these areas. The collaborations page contains photographs of some of my mentors, collaborators, co-authors, and cherished colleagues.
