Description of Research Expertise

Research Interests
Role of platelets in thrombus development

Key words: platelet; megakaryocyte; hematopoiesis; thrombosis.

Description of Research
My research efforts focus on the megakaryocyte-platelet-thrombus axis. The process by which hematopoietic stem cells differentiate into megakaryocytes, which then release platelets and the function of platelets in thrombosis and inflammation are the central foci of my laboratory. Many of the studies focus on the biology and pathobiology of the platelet-specific proteins, chemokines Platelet Factor 4 (PF4)/Platelet Basic Protein (PBP) and the integrin alphaIIb/beta3 receptor.

Rotation Projects for 2006-2007
1. Murine models of thrombosis.
2. Regulation of megakaryocyte gene expression.
3. Gene therapy lentiviral studies for bleeding disorders. Chemokine sin thrombosis and angiogenesis.
