Dr. Joshua Landvatter is a postdoctoral fellow in the Behavioral Sleep Medicine Laboratory at the University of Utah in Salt Lake City. After completing bachelor’s degrees in Spanish and Psychology, he pursued his master’s and PhD in Social Health Psychology from the University of Utah, where he investigated psychophysiological mechanisms underlying interpersonal relationships and their effects on cardiovascular, immune, autonomic, and inflammatory health. His research highlights the role of dyadic processes in influencing health outcomes, particularly how a partner’s health behaviors can significantly impact one’s own well-being. His work also explores the mediating role of sleep on self-rated health and inflammation, adding to the growing understanding of the relationship between psychosocial factors and physiological health.

His clinical background has informed his research focus, enabling him to approach health behavior from both a clinical and behavioral science perspective. He is committed to advancing research that integrates relationship science and behavioral medicine to support resilience and health across the lifespan.
