His research focuses on gravitational wave physics, black hole binary dynamics, and active galactic nucleus (AGN) interactions, with particular emphasis on eccentric orbital mechanics, gas-assisted mergers, and environmental perturbations in compact object systems. He utilizes numerical simulations to model gravitational wave signatures and study the outcomes of stellar evolution in extreme astrophysical environments.

Recent publications highlight trends in gravitational wave astronomy, including studies on:

• Eccentric features in dynamically formed black hole binaries
• Gas-driven mergers in AGN discs
• Environmental effects on gravitational wave signals
• Proper motion constraints for lensed neutron star mergers

He collaborates extensively on topics such as three-body gravitational interactions, mini-AGN disc formation, and dynamical friction in elliptical orbits, with a strong focus on connecting observational gravitational wave data to theoretical astrophysical models.

His work is published in leading journals like Astrophysical Journal, Monthly Notices of the Royal Astronomical Society, and Physical Review D, demonstrating expertise in both theoretical and computational astrophysics.
