Dr. James Head an Emeritus Professor of Physiology and Biophysics at Boston University School of Medicine. His research work focuses on characterizing the molecular details of protein-ligand and protein-protein interactions and the mechanisms by which changes in these interactions regulate physiological processes. These studies have concentrated mainly on the role of the calcium ion in mediating changes in protein-ligand interactions which subsequently may alter protein-protein interactions to modulate function. However, other protein-ligand interactions are also under study including enzyme-effector and protein-protein complexes. X-ray crystallography is a major tool used in these studies.
