I develop and use classical mechanical simulation methods to study the kinetics and thermodynamics of complex biological processes. I am specifically interested in performing all-atom simulations that can reach timescales of milliseconds and longer, with the aim to bridge gap between theory and experiments. As these timescales are far beyond the reach of the fastest supercomputers, my work entails the use of variety enhanced sampling algorithms to understand the dynamics of biomedically relevant biomolecules. Currently, I am working on characterizing the transition cycle of human glutamate transporters using advanced simulation techniques like: ConstantpH, Metadynamics, SMD, and Pathway sampling methods. Apart from this I also work actively on understanding the role of membrane environment and inhibitors in modulating the structure-function relationship of membrane proteins like: P-glycoproteins, Potassium-channels, and signalling domains.
