I am a graduate student in the Department of Physics at Penn State.

Binary neutron star mergers provide excellent laboratories for probing/testing nuclear physics at extreme densities- the kind which are not replicable on Earth. My research includes modeling these mergers via a combination of strong gravity and hydrodynamics and studying the allied high energy phenomenon.

In particular I am interested in studying several aspects of QCD phase transitions from hadrons to quarks in Neutron star cores as they evolve in a binary system and possible gravitational wave imprints which can be detected by 3rd generation gravitational wave detectors.

Other research interests include development of numerical methods for relativistic hydrodynamics.
