Overview
I study gravitational waves (GWs), extremely faint ripples in the fabric of spacetime caused by the mergers of compact objects such as black holes or neutron stars. The characteristic shape of GW signals allows us to uncover the source properties such as masses and spins of the compact objects.
I analyse both real as well as simulated GW signals that are detected by ground-based GW detectors (such as LIGO, Virgo, and KAGRA) to infer the physical and astrophysical properties of black holes or neutron stars in binaries. I also exploit the collective properties of many compact binary mergers to constrain their evolutionary and formation pathways.

Research
Low latency parameter estimation of compact binary mergers
Rapid parameter inference of the source properties of gravitational-wave (GW) signals is crucial for multimessenger follow-up observations. However, the stochastic methods currently used for the inference of GW signals from compact binary mergers are computationally expensive, often taking from hours to days. I work on developing the parameter inference routines based on the intuitive understanding of the GW signal to measure the astrophysical parameters in minutes.
