About

Welcome to my homepage! I am an Assistant Professor in the Department of Physics at the Indian Institute of Technology Kanpur. My research focuses on physics beyond the Standard Model, early universe cosmology, and LHC phenomenology.

Before joining IIT Kanpur, I held postdoctoral positions in France and Italy, including appointments at Γ‰cole Polytechnique, IJCLab Orsay, and INFN Rome. I obtained my Ph.D. from the Centre for High Energy Physics (CHEP), IISc Bengaluru.

I am actively involved in developing numerical packages for high-energy physics, including HEPfit and SuSeFLAV. My current research interests include dark matter phenomenology, early universe dynamics, and Higgs physics.

Research Areas

Dark Matter Physics

Investigating dark matter production mechanisms and their cosmological implications.

Early Universe Cosmology

Studying cosmological epochs prior to the Big Bang nucleosynthesis and their impact on dark matter abundance.

LHC Phenomenology

Implications of collider searches for physics beyond the Standard Model.
