Associate Professor

Download Curriculum Vitae

Dr. Mizuno earned his doctroral degree in 2005 from Waseda University in Tokyo, Japan. He completed a postdoctoral fellowship at UT Southwestern in 2009 and then joined the faculty in 2011. He is currently an active member of the American Physiological Society, American College of Sports Medicine and American Heart Association.

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.
