Being a biophysicist by training, I investigate fundamental processes of life at molecular level. I employ methods like x-ray diffraction or single-particle cryo electron microscopy to obtain structures of biological macromolecules. Moreover, I investigate interactions of these molecules by biophysical and biochemical methods to understand the underlying molecular mechanisms for basic cellular processes such as signal-transduction, protein trafficking and enzyme regulation etc. Besides, I produce engineered molecules with predicted properties to further corroborate my findings. The research has impact in basic sciences as well as drug research and development.
