Faculty Bio

We conduct research in the field of computational biochemistry and biophysics, focusing on the development and application of computational methods to understand the structure, dynamics, and thermodynamics of important biochemical processes such as protein-ligand and protein-protein interactions, DNA-ligand recognition, and conformational dynamics of proteins and nucleic acids. Our research is supported by active grants from NIH.
