About

Welcome to my homepage! I am an Associate 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 École Polytechnique, IJCLab Orsay, and INFN Rome. I received my Ph.D. from the Centre for High Energy Physics (CHEP), IISc Bengaluru.

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