Research Interests
Samit’s research interests lie at the interface of Mathematics, Biology and Statistics. Using mathematical tools such as nonlinear dynamics, game theory and optimization, he tries to understand complexities at the population and individual level of ecology and evolution of infectious diseases of humans and wildlife, including childhood infections and emerging infectious diseases. Specifically, he is interested in spatiotemporal dynamics of infectious disease, ecology of disease and management, impact of social norms and human behavior in disease and policy making.

Executive Summary
Dr. Samit Bhattacharyya started his Mathematical Biology research career modelling population dynamics of insect pest and their management in Ph.D. In the past few years, his research spanned over modelling human infectious disease like measles, whooping cough (pertussis), meningitis, and influenza. He implements both qualitative approach of modelling such as agent-based models, spatial models, stochastic models, network models to get insights into the basic biological processes; and quantitative approaches such as data analysis and statistical inference that helps to evaluate alternative hypotheses about these processes.
