Research Interests

Infectious diseases: structural and biochemical studies on bacterial adhesions/virulence factors-host interactions:

Dr. Ganesh’s research focuses on structural studies (X-ray crystallography and computational modeling) of Staphylococcus aureus adhesions/virulence factors-host interactions. Currently we are studying several key staphylococcus aureus virulence factors such as Clumping factors A and B, Immune system subversion protein Bbp, SdrC and secreted protein Efb’s  interactions with the host molecules. We have determined the crystal structure of ClfA in complex with a ligand derived peptide and ClfA in complex with an inhibitory therapeutic antibody that has led to the understanding on the binding and inhibition mechanism. Development of specific peptide based inhibitors of ClfA is underway and we are also interested in developing small molecule inhibitors.
