Rollin McCraty, PhD
Director of Research at HeartMath Institute

Rollin McCraty, PhD, is director of research at the HeartMath Institute. As a psychophysiologist, Rollin’s research interests include the physiology of emotion — with a focus on the mechanisms by which emotions influence cognitive processes, behavior, and health — and the global interconnectivity between people and the Earth’s energetic systems. Findings from this research have been applied to developing tools and technology to optimize individual and organizational health, performance, and quality of life.

Rollin has acted as principal investigator in numerous research studies examining the effects of emotions on heart-brain interactions plus autonomic, cardiovascular, hormonal, and immune system function. He has also served as principal investigator in many field studies to determine the outcomes of positive emotion-focused interventions and heart-rhythm feedback in diverse organizational and educational settings, as well as in various clinical populations.
