We study function and regulation of proteins involved in blood coagulation, the molecular mechanism of zymogen activation and auto-activation, and the rational engineering of protease specificity for therapeutic and biotechnological purposes. Also of interest is ligand binding theory and kinetics. Our approach utilizes rapid kinetics, thermodynamics, spectroscopy and x-ray crystallography.
