Dr. Hetrick is a clinical psychologist and neuroscientist whose research focuses on the behavioral, cognitive, and biological bases of severe psychological disorders, such as schizophrenia, autism, and cannabis use. His laboratory uses behavioral, cognitive, and electrophysiological methods, including EEG, EMG, MRI, and brain stimulation techniques. A specific focus of his research lab over the past decade has been the study of cerebellar involvement in psychological disorders. With his students and collaborators, he has published over 150 peer-reviewed papers and secured strong research funding from the National Institutes of Health (NIH). His teaching focuses on clinical and translational research, dimensional approaches to psychopathology, and clinical psychology at both the undergraduate and doctoral levels. He was the recipient of the IU Trustee’s Teaching Award in 2007 and 2012. He is involved in research training of psychology, neuroscience, cognitive science, and psychiatry doctoral students. He serves as director of a National Institute of Mental Health predoctoral T32 Research Training Grant focused on clinical translational research.
Professor Hetrick’s work is increasingly focused on global mental health and clinical neuroscience in East Africa, specifically in Kenya and Uganda. Three primary goals motivate this work. First, opportunities to conduct innovative, cutting-edge clinical research in partnership with African colleagues are unparalleled, given the long-standing IU-led AMPATH program. Prof. Hetrick has cultivated partnerships with faculty at AMPATH’s partner organization, Moi University, in psychology, psychiatry, medical physiology, and pediatrics. Thus, we have robust infrastructure and a strong interdisciplinary team in place to conduct and support global mental health and human clinical neuroscience. Second, there is the major problem of “WEIRD” science (Henrich, Heine, & Norenzayan, 2010). This refers to that fact that 80% of social and behavioral science studies are conducted with participants from Western, Educated, Industrialized, Rich and Democratic (WEIRD) societies, despite the fact that such participants constitute only 12% of the world’s population. As Henrich et al. (2010) noted, “Behavioral scientists now face a choice – they can either acknowledge that their findings in many domains cannot be generalized beyond this unusual subpopulation (and leave it at that), or they can begin to take the difficult steps to building a broader, richer, and better-grounded understanding of our species.” In close partnership with faculty and students in Kenya, our goal is to conduct clinical research studies focused on issues that are critical to East Africa, led by East Africans, and for the benefit of East Africans. Such research will make seminal contributions to the diversity, equity, and generalizability of psychological science. Finally, our work in Africa is motivated by a deep commitment to develop and expand clinical research infrastructure and expertise, which is typically unavailable in low- and middle-income countries. With Drs. Megan McHenry and Eren Oyungu, we established the first-of-its-kind human clinical neuroscience and experimental psychopathology laboratory at Moi University in Eldoret, Kenya. We also have sponsored an annual multi-institution, national neuroscience conference to foster education and training. Africa is home to nearly one fifth of the world’s population and has the fastest growing population on any continent. Further, with 60% of its population under 25 years of age, it is the world’s youngest continent. These observations underscore the vast opportunities to have a major impact in the development of new, young generations of clinical psychological scientists and mental health researchers. Accordingly, Prof. Hetrick is interested in prospective graduate students who are interested in global/international clinical psychological science and cognitive neuroscience. Students interested in EEG methods, computerized psychological, motor, and clinical assessment and cross-cultural psychology are especially welcome to apply to work with Prof. Hetrick within the support of the CCNC.
