Research highlight

I am an astrophysicist with diverse interests spanning gravitational physics, high-energy phenomena associated with compact objects, and dynamical systems theory. Specifically, my research i) involves examining observational signatures within both electromagnetic and gravitational spectra to scrutinize the principles of general relativity; and ii) navigates the dynamics of nonlinear waves within the realm of partial differential equations, where a fascinating interplay of mathematics and physics unfolds.
