Research Interests
Our research is primarily focused on understanding the mechanism by which coagulation proteases interact with their target cofactors, substrates, and inhibitors, and how heparin enhances the inhibitory function of antithrombin in the regulation of the proteolytic activities of these proteases. Another project in the lab focuses on understanding the mechanism by which coagulation proteases interact with endothelial cell surface receptors to elicit diverse intracellular signaling responses. We employ biophysical, biochemical, and molecular biological approaches to study these questions.
