I am a theoretical physicist working on astro-particle physics and high energy physics. Currently, I am a Research Associate in the Theory Division at Fermi National Accelerator Laboratory (Fermilab) and an Associate Fellow at the Kavli Institute for Cosmological Physics (KICP), The University of Chicago. I was a postdoctoral research scholar at the Department of Physics, Pennsylvania State University (2022- 2025) with Prof. Kohta Murase as my mentor. I completed my Ph.D. in Physics at Arizona State University (2018 - 2022) , where I worked with Prof. Cecilia Lunardini (advisor) and Prof. Tanmay Vachaspati. I completed my undergrad (Bachelor of Science - Physics (Honors)) at St. Stephen's College, University of Delhi (2015 - 2018).

I am an astroparticle physicist exploring how cosmic particle accelerators reveal the most energetic processes in the Universe and probe the Standard Model of particle physics and beyond. My work spans multi-messenger astrophysics and theoretical high-energy physics/cosmology, using neutrinos, gravitational waves, and electromagnetic signals as complementary probes. On the astrophysics side, I study the phenomenology of astrophysical neutrinos, dark matter, and emissions from astrophysical sources like supernovae, neutron star mergers, gamma-ray bursts, active galactic nuclei, and tidal disruption events. On the cosmology side, my work has focused on the dynamics of quantum fields in time- and space-dependent backgrounds, investigating particle production, backreaction, and early-universe phase transitions leading to the formation of topological defects and their dynamics.
