Dr. Goodnight is an assistant professor in the Department of Psychology. He received his B.S. in psychology from Xavier University, and received his Ph.D. in Clinical Psychology from Indiana University. He came to Dayton in 2010, following the completion of his clinical internship at the Institute for Juvenile Research at the University of Illinois - Chicago. He teaches courses in Abnormal Psychology, Developmental Psychopathology, and Family and Couple Therapy.

Dr. Goodnight’s research program seeks to identify factors that can help explain individual differences in susceptibility to social influences (e.g., deviant peer) that promote the development of aggressive and delinquent behavior in childhood and adolescence. He also uses genetically-informative designs to evaluate putative environmental risk factors for conduct problems.
