Tommy K. Begay, PhD, MPH

Research Assistant Professor

Dr. Begay is Research Assistant Professor in the Department of Psychiatry, College of Medicine, University of Arizona (UA). He is a Cultural Psychologist by academic training, focusing on the interrelationship of culture, biology, and environment, to understand human behavior as applicable to health, and wellness. From this approach, cognition and human development – specifically, neurodevelopment and neuroplasticity – depend upon environmental stimulation provided through social interaction, context, and culture. Basically, all activities and behaviors lend to physical and functional changes to the brain – and changes to the brain influence behavior. The results collectively contribute to consciousness, identity, and personality.

Dr. Begay possesses a Master of Public Health degree, with a specialty in International Health, from the UA MEZ College of Public Health. He completed his Postdoc training at the UA Department of Psychiatry. As an Instructor at the UA, Dr. Begay has taught the following courses: American Indian Medicine and Wellness, Drugs and Society, Human Sexuality, Health Education Intervention Methods, and Contemporary Community Health. Prior to obtaining his doctorate, Dr. Begay worked as Program Director in the Native American Research and Training Center, and the MEZ College of Public Health, at the UA.

Research Interests

Dr. Begay’s research interests include Native American health, especially in relation to the impact of American Indian historical trauma, and the subsequent evolution of intergenerational, maladaptive coping behaviors that contribute to the disproportionately high rates of stress-related chronic diseases, cancer, interpersonal violence, accidents, substance abuse, and addiction – all major contributing factors to the contemporary health and wellness of American Indians and Alaska Natives. Of particular interest is the use of psychoneuroimmunology to assess the health impact of chronic stress, and the physiological responses associated with psychological trauma. In this regard, Dr. Begay has laboratory experience coordinating the collection, cataloguing, and storage of biological samples necessary for stress response and inflammatory biomarker assay and analysis. Understanding the biology of traumatic stress reactions lend to intervention and prevention strategies that help align the body, mind, and spirit back into balance.

Originally from Dinétah, the Navajo Nation, Dr. Begay currently resides in Tucson, Arizona. There he provides psychosocial health education lectures, seminars, and workshops on topics relevant to behavior modification and behavioral health. Often, focusing on the developmental process of the “culture of maladaptive behaviors” (self-medication, addiction, and violence) linked with toxic stress, adverse childhood experiences, and maladaptive coping skills. Factors associated with self-harm, substance abuse, violence, and low academic achievement – potential antecedents of poor health, criminal behavior, and mortality.
