Dr. Fitzgerald’s research group is focused on studies of protein folding and function. The group utilizes a combination of covalent labeling strategies (e.g. protein amide H/D exchange and methionine oxidiation) and mass spectrometry techniques to investigate the thermodynamic properties of protein folding and ligand binding reactions. Current research efforts involve: (1) the development new biophysical methods that enable protein folding and stability measurements to be performed on the proteomic scale; and (2) the application of these new methods in the areas of disease detection, diagnosis, and therapy.
