My area of research is Hyperspace Topology and Generalized Topology. Nowadays I am working on Selection Principles in Hyperspace Topology.
B. Sc. in Mathematics (University of Calcutta, 2002)
M. Sc. in Pure Mathematics (University of Calcutta, 2004, stood first class first)
Ph. D. in Pure Mathematics (University of Calcutta, 2010)
After my M. Sc. I joined Bethune College as a full-time lecturer under Tarak-Sudha Fellowship in 2004. Then I joined CSIR as a research fellow on 01.03.2006. In September 2008, I joined Seth Anandram Jaipuria College as an Assistant Professor. Then on 09.11.2016 I joined Presidency University.
