My current research primarily focuses on understanding the nature of dark matter and exploring its potential connection with other sectors of physics beyond the Standard Model (BSM), particularly concerning the origin of the baryon asymmetry and neutrino masses. During the course of my Ph.D., my research delves into understanding the dynamics of extended dark sectors involving multiple and asymmetric dark matter (ADM) components, and studying neutrino mass models and their implications for baryogenesis via leptogenesis.
