Biography+
After completing M.Sc I worked as an Assistant Teacher at Satyabhama Institution in 1994. During 2001 I started my doctoral work under the supervision of Dr. C.R. Mandal, Jadavpur University. Title of my thesis: Theoretical Studies on Inelastic Processes in Collisions of Heavy Ions with Atoms at Intermediate and High Energies. After finishing my doctoral work I moved to a fellowship at Tata institute of Fundamental Research, Mumbai in 2007. Then I joined at Haldia Government College as an Assistant professor in Physics in 2009. In 2010 I moved to Ramakrishna Mission Residential College (Autonomous), Narendrapore, Kolkata. I left the job there in 2018 to enable me to join at Presidency University.
