Black holes in strong field gravity, Gravitational waves, Numerical relativity

"One of the major successes of the current century is the achievement of stable, long term non-linear numerical evolutions involving black holes. This is followed by the recent astrophysical detections of gravitational waves from merging black holes and other compact objects by LIGO-VIRGO-KAGRA, in which the numerical relativity simulations played a seminal role.

Although the physics of black holes have enticed researchers since decades, most progress in their understanding centers around scenarios involving stationary/static black holes, and perturbations thereof. In astrophysical scenarios such as binary black hole mergers, the black holes exist under the strong gravity influence of each oth er, and are highly dynamical, especially as they close in towards the merger.

One of my main interests is to understand the physics and astrophysics of black holes in such highly dynamical scenarios. I study the physics of black holes and their horizons in dynamical regimes using dynamical horizons and numerical relativity, and their imprints in the gravitational radiation received at infinity where gravitational waves are detected. I am also interested in the associated observational and computational aspects.
