 Personal Statement

Dr. Gonzales has 20 years of experience conducting applied physiology studies in humans. He currently directs the Vascular Aging Laboratory where he has been an independent investigator since 2010. Dr. Gonzales has been funded by the National, Heart, Lung and Blood Institute (pre-doctoral award, 2006-2008), the National Institute on Aging (post-doctoral award, 2008-2010), and the American Heart Association (2015-2017 and 2019-2021). His current research examines i) the impact of age-related vascular dysfunction on physical function, and ii) how sleep alters vascular and cognitive function in middle-aged to older adults.
