About us

The Psychophysiology and Stress Research Group (PSRG) seeks to explore the relationship between psychosocial stress, well-being and health and determine the physiological pathways that mediate such associations. The group examines the role of the HPA axis as a mediator of these links and has particular expertise in measurement of the cortisol awakening response.
