Research Interest

Dendritic Polymers: The conformational and dynamic properties of dendrimers and randomly hyperbranched polymers are explored in the framework of optimized Rouse-Zimm models as a function of flexibility and excluded volume parameters and generational growth.


Proteins: State-of-the-art computational and theoretical techniques are used to study the structure and dynamics of protein and its environment. A major goal is to understand protein misfolding, intrinsic disorder and fold switch through sequence design and sequence analysis.
