Sarif Khan is a particle physicist with a focus on physics beyond the Standard Model (BSM) of particle physics. He completed his Master and PhD degrees at the Harish-Chandra Research Institute, India, in 2015 and 2019, respectively. During the final year of his PhD, he moved to the University of Goettingen, Germany, as an MSCA ITN Early Stage Researcher. After successfully defending his PhD thesis in 2019, he continued at the University of Goettingen as a Research Associate, where he worked until 2024. Following the completion of his postdoctoral tenure in Germany, he joined Chung-Ang University, Seoul, as a Brain Pool Research Professor. With extensive experience in various aspects of BSM physics, he has worked for several years on dark matter production using state-of-the-art production mechanisms. In addition to dark matter, his research interests include baryogenesis, inflation, neutrino mass generation, and collider phenomenology. He also has expertise in numerical simulations and experience using high-performance computing (HPC) facilities. Combining sound theoretical knowledge with advanced computational skills, he aims to fully utilise his MSCA Postdoctoral Fellowship at the University of Padova. Through his project, DLEAD, he plans to further deepen his expertise in dark matter, leptogenesis, and inflation, with a particular focus on low-reheating cosmological scenarios.
