I joined Presidency University as Assistant Professor of Mathematics in January' 2013. My research interests are in qualitative analysis of differential equations with its applications in many physical and biological systems.
Ph. D. Applied Mathematics (University of Calcutta, 2010)
M.Sc. Applied Mathematics (University of Calcutta, 2002)
B.Sc. with Mathematics Major (Berhampore K.N. College, 2000)
After completing my Masters I joined the Department of Applied Mathematics, University of Calcutta as CSIR-UGC junior research fellow to persue my doctoral work under the supervision of Prof. C.G. Chakrabarti (S.N. Bose Professor of Theoretical Physics, now retired). During my doctoral research I got my first appointment as lecturer at Scottish Church College, Kolkata. In 2007, I was appointed as lecturer at Haldia Government College under WBES. I was awarded the Ph. D. degree in 2010 and finally, I joined Presidency University in January, 2013.
