Brett R. Blackman, Ph.D.


Chief Scientific Officer


“Since our inception, HemoShear has been about providing transformative solutions using human relevant systems for our drug developing partners and supporting our collective mission in providing safe and effective therapies to improve global human health.”


Dr. Blackman is co-founder of HemoShear and co-inventor of its technology. He is a tenured Associate Professor in the Department of Biomedical Engineering at the University of Virginia (UVa) where since August 2002 he has led an NIH-funded research program investigating the role of the hemodynamic environment in regulating vascular endothelial cell biology in atherosclerosis. Prior to joining UVa Dr. Blackman trained as a postdoctoral research fellow in the Vascular Research Division of Brigham & Women’s Hospital and Harvard Medical School, where he developed the first cell-culture system to simulate human hemodynamic patterns on isolated human endothelial cells. This work laid the foundation for current research identifying the importance of precise hemodynamic conditions for regulating arterial vascular biology. Dr. Blackman has published more than twenty peer-reviewed articles, was a co-editor of Hemodynamics and Mechanobiology of the Endothelium, is a member of the Robert M. Berne Cardiovascular Research Center, is a peer reviewer for more than twelve scientific journals, served on UVa’s School of Engineering and Sciences Dean’s Research Advisory Committee, and was a standing member of the American Heart Association Bioengineering & Biotechnology study section.

Brian R. Wamhoff, Ph.D.


Vice President of Research and Development


“Our scientific teams are amazing, the science is translational, and I have never worked in a more exciting environment!”


Dr. Wamhoff is co-founder of HemoShear and co-inventor of its technology. He is an Associate Professor at the University of Virginia (UVa) in the Cardiovascular Division of UVa’s Department of Medicine, with a joint appointment in Biomedical Engineering. Dr. Wamhoff has expertise in small and large animal models of vascular disease, molecular biology and cell-based systems and interventional vascular device development. He has obtained funding from the NIH, the pharmaceutical industry, the American Heart Association, and other organizations to study fundamental mechanisms that regulate smooth muscle cell biology vascular disease. Dr. Wamhoff has authored more than 50 peer-reviewed manuscripts, as well as several book chapters and commentaries. Dr. Wamhoff has also received multiple awards for his successes, including the 2004 American Physiological Society Cardiovascular Young Investigator Award, the 2008 Atherosclerosis, Thrombosis, and Vascular Biology (ATVB) Irvine H. Page Award, the 2010 American Physiological Society New Investigator Award for Cardiovascular Research and the 2011 Rhodes College Distinguished Alumni Award, his alma mater. Dr. Wamhoff obtained a BS in Biology with a minor in Business Administration from Rhodes College in 1996 and received his PhD in Medical Physiology from the University of Missouri in 2001.
