Masaki Mizuno, Ph.D. Titles and Appointments Associate Professor School School of Health Professions Department Applied Clinical Research | Internal Medicine Biography Download Curriculum Vitae Dr. Mizuno earned his doctoral degree in 2005 from Waseda University in Tokyo, Japan. He completed a postdoctoral fellowship at UT Southwestern in 2011 and then joined the faculty. He is currently an active member of the American Physiological Society, the American Heart Association, and Fellow of the American College of Sports Medicine. Dr. Mizuno's laboratory has been studying autonomic control of the cardiovascular system. Current research focuses on examining the mechanisms underlying alterations in circulatory control in type1 or type2 diabetes. More specifically, the lab is actively investigating the central and peripheral mechanisms underpinning the abnormal elevations in sympathetic nerve activity that accompany the pathogenesis of these diseases.
