My current research primarily focuses on addressing some of the fundamental challenges associated with nanoscience. Specifically, this research tries to answer some of the open questions pertaining to the electron (both charge and spin) transfer process involving nanoscale junction in a non-equilibrium condition using quantum many body theory.
