Research Interests

Macromolecular Crowding, Protein folding and aggregation.
Our group is focusing primarily on different aspects of macromolecular crowding and its influence on protein conformation and dynamics using a range of tools, like FRET, Solvation dynamics and fluorescence correlation spectroscopy (FCS). We have also been involved in probing the effects of polyphenols on the aggregation properties of various proteins.
