Dr. Richard J. Simpson


Dr. Simpson is a Professor in the School of Nutritional Sciences and Wellness (College of Agriculture and Life Sciences) at the University of Arizona and hold joint appointments in Pediatrics (College of Medicine), Immunobiology (College of Medicine), the Arizona Cancer Center and the Bio5 Institute. His research is concerned with the effects of exercise on the immune system in the context of cancer, aging and human performance. Major focus areas include understanding (1) how exercise and other behavioral interventions can offset age-related decrements in the normal functioning of the immune system (immunosenescence), (2) how exercise-induced adrenergic receptor signaling can be used to improve anti-cancer immunity and augment the manufacture and efficacy of cancer therapeutics, (3) the interplay between the immune and neuroendocrine system during high level human performance and extreme isolation (e.g. space travel), and  (3) how the immune system can be manipulated to develop potent cell therapies that will help eliminate cancer. He is the current president-elect of the International Society of Exercise Immunology (ISEI), a fellow of the American College of Sports Medicine (ACSM) and sits on the editorial boards of the following journals: Brain, Behavior and Immunity; Exercise Immunology Reviews (Associate Editor),  Immunity and Ageing, and the ACSM journal Exercise, Sport and Movement. Dr. Simpson is a member of the expert committee on mechanisms for the next phase of the World Cancer Research Fund (WCRF)/American Institute for Cancer Research (AICR) Continuous Update Project (CUP), which is working to develop a clearer understanding of the biological processes which underpin associations between diet, nutrition and physical activity and cancer. He has published over 120 peer-reviewed articles and book chapters and has served as the primary mentor for >20 PhD students and postdoctoral scientists. His current/recent research is supported by NASA, the National Institutes of Health (NIH) and industry.
