Research Interests

Central to the ability of vascular cells to adhere to the extracellular matrix and to each other is an abundant supply of cell surface adhesion molecules that, in addition to influencing the adhesive phenotype of the cell, are also capable of transmitting signals into, and responding to signals from, the cell interior (often referred to an outside/in and inside/out signal transduction, respectively). Such post-ligand events occur by virtue of the ability of these transmembrane proteins to interact with intracellular kinases and phosphatases, G-proteins, adapter proteins, and cytoskeletal components. Our laboratory divides its attention between exploring the role of stimulatory and inhibitory receptors in regulating adhesion and aggregation of human and murine platelets (funded through a Program Project grant), and the structure and function of PECAM-1 in the blood and vascular cells in which it is expressed (funded through a long-standing R01). Techniques range from biochemistry to molecular biology to whole animal models of thrombosis and hemostasis.
