My research focuses on designing computational and mathematical models for biological processes. Two types of the processes I am currently studying are electrical activity of neurons and dynamics of regulatory molecular networks. A mathematical aim of my research is to develop common modeling approaches that can be used for analysis of a wide range of systems. Other aims are specific for every project and depend on the biological system I model. Currently, the major direction of my research is mathematical modeling of how addictions change the brain circuitry and function. I am designing a model of the brain circuitry that is responsible for goal-directed learning and hijacked in addictions - the dopamine system and its feedback mechanisms. The project offers an exceptional opportunity to connect experiments at different levels by modeling and achieve deep understanding of how specific addictive drugs targets produce its system level effects.
