Research Interests

Delineated mechanisms responsible for altered fibrinolysis in the blood of patients with diabetes.  Demonstrated that the combination of hyperinsulinemia, hyperglycemia and increased concentrations of free fatty acids in blood of healthy subjects increases the concentration and activity of the primary inhibitor of fibrinolysis, plasminogen activator inhibitor type 1 (PAI-1).  With studies in vitro that demonstrated increased concentrations in blood of insulin increase expression of PAI-1 through stabilization of mRNA.  In addition demonstrated that free fatty acids increase expression of PAI-1 by increasing transcription of PAI-1 through a fatty acid response region in the 5’ untranslated region of the PAI-1 gene.

Developed assays for assessing platelet function that utilize flow cytometry to characterize specific components of platelet reactivity.  Demonstrated the prognostic implications of platelet reactivity to characterize the effects of selected condition, and treatments on platelet function.  Assessing new methods to identify patients likely to exhibit consistently increased platelet reactivity.

Identified factors that influence platelet function by increasing platelet reactivity.
