Dr. Isaac T. Petersen is an Assistant Professor at the University of Iowa. He completed his Bachelor of Arts in Psychology and French at the University of Texas, his Ph.D. in Psychology at Indiana University, and his clinical psychology internship from Western Psychiatric Hospital at the University of Pittsburgh Medical Center.

Dr. Petersen is a licensed clinical psychologist with expertise in developmental psychopathology. His clinical expertise is in training parents how to deal with difficult children. He is interested in how children develop individual differences in adjustment, including behavior problems as well as competencies, so that more effective intervention and prevention approaches can be developed and implemented. He is particularly interested in the development of externalizing behavior problems (e.g., ADHD, conduct problems, and aggression) and underlying self-regulation difficulties. Dr. Petersen's primary interests include how children develop self-regulation as a function of bio-psycho-social processes including brain functioning, genetics, parenting, temperament, language, and sleep, and how self-regulation influences adjustment. A special emphasis of his work examines neural processes underlying the development of self-regulation and externalizing problems, using electroencephalography (EEG) and event-related potentials (ERPs). He uses longitudinal designs, advanced quantitative methods, and multiple levels of analysis, including bio-psycho-social processes, to elucidate mechanisms in the development of externalizing problems. His work considers multiple levels of analysis simultaneously, in interaction, and over lengthy spans of development in ways that identify people's change in behavior problems over time while accounting for the changing manifestation of behavior problems across development (heterotypic continuity).
