Research Interests

Theoretical and Computation Biological Physics

The main motivation and goal of my research in biological physics is to  understand how living matter is organized and functions at different (e.g., atomic or microscopic, sub-cellular or mesoscopic) levels. In my research, I employ and develop computational methods widely used in molecular modeling (e.g., large scale, parallel molecular dynamics simulations, molecular visualization, stochastic modeling and analysis), as well as, analytical methods used in theoretical physics.

The type of problems I am currently working on are related to: mechanical force generation and signaling mechanisms in G-proteins, force transduction by motor proteins, effect of static and dynamic disorder (thermal fluctuations) on energy transfer in light harvesting proteins, mass and charge transport in transmembrane channel proteins, reconstruction of potential of mean force from non-equilibrium molecular dynamics simulations, and aggregation phenomena in biological systems.
