is the shortest route. Welcome to my office only with prior
appointment via email.Welcome to Supratik's world ….
I am a Physicist working on Cosmology and Astroparticle Physics. Broadly, I am interested in anything related to evolution history of the universe. My work deals with theoretical aspects such as proposing new models and techniques, as well as observational issues via data analysis. I also enjoy my role in Science popularization, particularly to the younger generation. Because of my diverse research interests, I end up at migrating from one topic to the other. Believe me, it's real fun!
