My main research interests are in mathematical biology including, population dynamics, ecological problems and cell behaviour. One central aim is to understand when a biological system can be modeled at a deterministic population-based level, and when more individual-based stochastic approaches are required. My research uses mathematical models, applying methods from dynamical systems and stochastic processes together with computer simulations. My earlier work was on the ecological and epidemiological problems. My PhD thesis was on the problem cause by the diseases spread by the migratory birds. I have also studied the plankton dynamics with special emphasis on the Harmful algal bloom (HAB). My post-doctoral research (in Torino University, Italy) concerned with the biological control of crops. I tried to find out how effective spider is as a biological controller in a vineyard.
