I am a Professor of Mathematics at Jadavpur University, Kolkata, India. I did my masters with specialization in Operations Research and PhD in Mathematical Biology from Jadavpur University. Before joining Jadavpur University in 2001, I worked as a Lecturer at Serampur College, Hooghly and Dum Dum Motijheel College, Kolkata. In 2010, I became a professor and took the responsibility of the Centre for Mathematical Biology and Ecology. I founded, with my other colleagues, the Biomathematical Society of India in 2008. I was elected President, Mathematical Sciences (Including Statistics) Section of 106th Indian Science Congress, 2018-2019. My research interests include mathematical ecology, epidemiology, delay-differential equations, reaction-diffusion equations, nonlinear dynamics, discrete dynamical systems, ecological networks and systems biology.
