Research

My current doctoral research at the Florida Atlantic University involves numerical relativistic simulation of compact objects, focusing principally on neutron stars (NSs), under the supervision of Prof Wolfgang Tichy. Gravitational Wave (GW) observation events, along with counterparts in other accompanying spectra, ushered the current age of multimessenger astrophysics. Given this scenario, I worked on simulating neutron stars with three objectives: (i) improving the accuracy and efficiency of the simulating program, (ii) exploring new physics and NS configurations, and (iii) investigating GW observation events through tailored simulations.

Additionally, I have also worked on simulating black holes. Before my doctoral research, I studied Hawking radiation and Unruh effect, involving quantum field theory on curved space-time.

Below are all the projects that I am working on currently and have worked on in the past.
