Dr. Wray joined the Division of Geriatrics at the University of Utah as a Research Assistant Professor in 2008. He is a founding member of the Utah Vascular Research Laboratory (, a consortium that is affiliated with the University of Utah (Departments of Internal Medicine and Nutrition and Integrative Physiology) and the Salt Lake City Veterans Administration Medical Center Geriatrics, Research, Education and Clinical Center (SLC VAMC GRECC).

Dr. Wray maintains an active, extramurally-funded research program within the UVRL that is broadly focused on vascular and autonomic physiology, with an emphasis on aging and age-related diseases such as heart failure (HF). Current projects include studies examining neurohumoral control of muscle blood flow at rest and during acute exercise, and studies focused on determining the causes and consequences of chronic sympathoexcitation in HF.
