Dr. Thomas D. Parsons is an Associate Professor of Clinical Psychology. He is Director of UNT’s Clinical Neuropsychology and Simulation (CNS) lab. Prior to joining the UNT faculty, Dr. Parsons was on faculty at the University of Southern California. Dr. Parsons is a Clinical Neuropsychologist and his research focuses on the role of frontal subcortical circuits that underlie neurocognitive and affective regulation following trauma (e.g. brain injury; post-traumatic stress disorder); and/or neurological illness (e.g. HIV/AIDS; Alzheimer's Parkinson's). Much of his research integrates psychology and technology. In addition to his patent for eHarmony's Matching System, he has invented and makes use of virtual environments and artificial neural networks to assess the frontostriatal system's supervisory attentional system and adaptive responding to environmental situations.
