Research Interests

The research in our lab is on biochemistry and molecular biophysics, problems of protein folding, misfolding and aggregation, biomaterials, and biosensor. The research is directed towards understanding the structure, function and conformational dynamics of proteins. One of the aims is to understand the basic principles that govern protein folding in cellular environment and to explore the underlying mechanisms of amyloid diseases caused by protein misfolding and aggregation.
