I am currently interested in the quasinormal modes (QNMs) produced during black hole ringdown, when a perturbed black hole settles down into its stationary (Kerr) state.

In particular, I research the identification of QNMs, and quadratic QNMs that arise from second-order perturbation theory. Recently I published a paper on a novel method to determine the spatial structure of first and, in particular, second-order perturbations. Not only does this analysis provide a new way to detect QNMs, but it may inform future gravitational wave observations by, for example, giving an indication of the angle of maximum strain amplitude.

You can find my publications here.

More generally, I am interested in black holes, gravity, and ways to test fundamental physics using astrophysics and cosmology. I am also interested in the philosophy of physics.
