Atul Kedia
Dr. Kedia earned his Ph.D. in 2022 from the University of Notre Dame. He conducted postdoctoral research work at the Rochester Institute of Technology from 2022 to 2024 and at North Carolina State University from 2024 to 2026.
Dr. Kedia is an astrophysicist with a broad range of interests in multi-messenger and nuclear astrophysics pertaining to neutron stars. His research interests include nucleosynthesis, multi-messenger astrophysics, gravitational wave studies for neutron star mergers, the nuclear equation of state, and nuclear reaction rates in conducting elemental nucleosynthesis.
He works 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, and conducts nucleosynthetic studies revealing the connections between nuclear reaction rates and element formation.
