Research & Clinical Interests

Dr. McKenzie directs two major research projects. The first project involves vascular biology, with a focus on immune-mediated thrombocytopenia and thrombosis syndromes. This work, done in collaboration with Dr. Michael Reilly, led to the first model of heparin-induced thrombocytopenia and thrombosis. New work on effects of elevated cholesterol and athrosclerosis on HITT, and on microparticles and tissue factor, is ongoing.
