Nathan A. Call, Ph.D., BCBA-D
Director, Behavior Treatment Clinics
Dr. Call received his doctorate in school psychology from the University of Iowa in 2003 with the mentorship of David P. Wacker, Ph.D. He completed a predoctoral internship at the University of Iowa Hospitals and Clinics Center for Disabilities and Development, and he completed his postdoctoral fellowship at Marcus Autism Center and Emory University with the supervision of Wayne Fisher, Ph.D., and Henry S. Roane, Ph.D.
After working as an assistant professor at Louisiana State University from 2004 to 2006, Dr. Call has returned to Marcus Autism Center where he is currently the director of the Behavior Treatment Clinics. In addition to supervising postbaccalaureate and master’s level trainees, Dr. Call has an active research agenda that includes publishing in and serving on the board editors for several journals.
Dr. Call’s current research interests include the assessment and treatment of severe behavior disorders. This work led him to primarily work with children diagnosed with autism and other developmental disabilities and their families. His specific interests include identifying the basic behavioral mechanisms that influence the occurrence and maintenance of problem behavior, and developing clinical methods that incorporate these mechanisms into the assessment and treatment of problem behaviors. He also has an interest in identification and manipulation of the variables that impact the integrity with which caregivers implement behavioral treatment recommendations in the natural environment.
