Michael J. Alexander, MD, has led and participated in numerous research projects funded by the National Institutes of Health (NIH) and industry. Over the past five years, his clinical research has focused on four primary areas: brain aneurysms (for example, Alexander was the institutional principal investigator for the Liberty trial and the FRED flow diverter trial), atherosclerotic disease (cholesterol plaque) of the carotid arteries and cerebral arteries (Alexander was a leader on the initial steering committee of the NIH-funded SAMMPRIS trial, was the institutional principal investigator on the SAPPHIRE WW carotid stent trial, and was the national principal investigator for the WEAVE intracranial stent trial), acute embolic stroke (he was co-investigator of the NIH-funded MR Rescue stroke trial and institutional principal investigator for the POSITIVE, THERAPY, START and PICS stroke trials), and cerebral (brain) hemorrhage (he was co-investigator in the NIH-funded MISTIE 3 and CLEAR 3 intracranial hemorrhage trials).
