Atul Kedia is a postdoctoral Research Associate at CCRG working with Dr. Richard O'Shaughnessy. Atul received his PhD (and his MS) studying "Relativistic Matter in Neutron Star Mergers and Big Bang Nucleosynthesis" under Prof. Grant Mathews 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 presence of 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, kilonova physics and modelling, nuclear astrophysics, and the nuclear equation of state. With Dr. O'Shaughnessy, he is working on modelling the kilonova light curve emission for a broad range of ejecta configurations that results from various possible binary neutron star mergers, and on constraining the nuclear equation of state by astrophysical observations using a new adaptive inference code, named HyperPipe (part of RIFT).
