I Completed my Ph.D. in Applied Mathematics from Indian Statistical Institute, Kolkata. My research focuses on the mathematical modelling and analysis of infectious disease dynamics in ecological systems. I analyze deterministic models using systems of Ordinary Differential Equations (ODEs) and stochastic models formulated through Stochastic Differential Equations (SDEs), utilizing Itô calculus to capture the role of environmental randomness. My work aims to understand how demographic heterogeneity, transmission mechanisms, and ecological interactions influence disease spread, persistence, and control. I integrate model-based approaches with data fitting and statistical analysis to validate models and extract biologically meaningful insights, providing a robust framework for forecasting outbreaks and evaluating control strategies in both structured populations and fluctuating environments.
