Hans P. Nazarloo, M.D. Ph.D.

Senior research scientist

Dr. Nazarloo is trained in molecular neuroendocrinology, neuroimmunology and clinical cardiology. He has worked with Dr. Sue Carter at the University of Illinois at Chicago, Research Triangle Institute and University of North Carolina (originally as a Research Assistant Professor, then Research Associate Professor, and Senior Neuroscientist), where he developed his research with prairie voles. His research interest is to understand mechanisms through which stressors across the life-span regulate physiology and behavior.

Dr. Nazarloo has a long-standing interest in validation of the ELISA Assays and a better understanding of sex differences, especially as they related to female health and behavior. Currently, he is conducting exciting work on validating oxytocin in saliva as well as working on epigenetic mechanisms involved in the oxytocin receptor gene.
