Associate Member, Lindsley F. Kimball Research Institute
The Platelet Research Laboratory is interested in the pathobiology of platelets and platelet molecules. We are currently focused on improved diagnosis and novel therapeutics for heparin induced thrombocytopenia/thrombosis (HITT). We have recently published on novel assays which may improve the precision and accuracy for diagnosis HITT. Have also published on novel small molecules that interfere with the formation of heparin:PF4 complexes, which we call PF4 Antagonists (POF4As). We are actively working to improve the potency and pharmacology of PF4As towards the development of PF4As as a therapeutic option for the treatment and/or prevention of HIT. We are also interested in the pathgobiology of HIT as well as other platelet disorders.
