Atul Kedia is a postdoctoral research associate at CCRG working with Dr. Richard O'Shaughnessy. Atul received his PhD studying "Relativistic Matter in Neutron Star Mergers and Big Bang Nucleosynthesis" with Prof. Grant Mathews and Masters at the University of Notre Dame. He completed his undergraduate studies at the Indian Institute of Technology Bombay.

During his graduate studies Atul researched on the neutron rich environments in astrophysics and cosmology. He built numerical relativity based simulations (with the Einstein Toolkit) of the spectacular event of binary neutron star mergers and has worked on finding features in the gravitational wave that would indicate the occurance of a crossover to quark matter in the core. He also researched on the thermalization of nuclei in Big bang nucleosynthesis by analytic methods and simulations by developing a multi-dimension multi-specie special-relativistic thermalization code which can track the distribution of energy in these plasmas. During the undergraduate studies he conducted research on cosmology by finding a scale to cosmic homogeneity.

Atul's current research interests are in multi-messenger astrophysics, gravitational wave studies for binary neutrons star mergers, nuclear equation of state and nuclear astrophysics. With Dr. O'Shaughnessy, he is working on modelling the postmerger ejecta with a combination of results from numerical relativity based simulations and analytical solutions, and on generating surrogate light curve models for kilonovae resulting from binary neutron star mergers.
