B.Sc Mathematics (Jadavpur University, 2007)

M.Sc Mathematics (Jadavpur University, 2009)

Ph. D Operations Research (Jadavpur University, 2016)

DS Kothari Post-Doctoral Fellow (University of Burdwan)

I have completed my B.Sc in Mathematics, M.Sc. Mathematics (Specialization- Operations Research) from Jadavpur University, Kolkata. I have qualified CSIR-NET JRF on June 2010 and worked as a full-time research fellow to do my research in Operations Research under the guidance of Prof. Bibhas Chandra Giri (Department of Mathematics, Jadavpur University). After my Ph.D. I have worked at NIT Silchar on Ad-hoc basis for one semester. During that period I received DS Kothari Post-Doctoral Fellowship and leave my position at NIT Silchar to work under the supervision of Prof. Asoke Kumer Bhunia (Department of Mathematics, University of Burdwan). 

My Ph.D. work is based on two and three echelon supply chain models considering various types of market demand. The main focus during the initial phase of my work was on the price dependency of market demand. In the later part of my research I incorporate the effect of effort level and quality of the product on the market demand. I also worked on an integrated inventory model with unequal sized shipments.

During my time as a Post-Doctoral Fellow I have worked on green supply chain models. I am currently working on multi-period supply chain models.
