Research Interests

In vivo models of thrombosis and coagulation

My research is focused on using in vivo models to study the pathobiology of thrombotic, hemorrhagic and vascular diseases. We also develop and evaluate novel point-of-care assays to inform the management of these diseases.



These studies employ a variety of modern techniques including:

High speed intravital fluorescence widefield and confocal microscopy
Molecular biology
Murine genetics
Protein expression
Blood cell isolation
