Research Interest

Development and application of advanced spectroscopic methods and techniques. I worked towards understanding biomolecular interactions, characterizing live cells and stability testing of pharmaceutical formulations. My current research interest include mechanistic understanding of the phase behaviour and stability of complex fluids.
