Milad Najafichaghabouri

Dr. Najafichaghabouri completed his PhD in Disability Disciplines with a focus in Applied Behavior Analysis (ABA) from Utah State University. During his doctoral program, Milad served as a BCBA for the SPED department at a local school district. In this role, Milad assisted with assessment and treatment of challenging behavior for students receiving Tier 3 services within an MTSS framework. In addition, Milad also served as the lead graduate clinician for 3 years at the Behavior Support Services, an outpatient clinic serving with challenging behavior. Milad also served as primary instructor or teaching assistant for numerous graduate level courses in ABA and single-case design methodology.

Milad’s research at Utah State University forced on use of effective class-wide intervention in general education classrooms. He has published multiple peer-reviewed articles and book chapters on this topic. Milad is also very passionate about improving social validity practices in ABA research and practice and is interested in identifying novel ways that we can improve the way we program for and measure social validity.

Milad is very excited to bring his clinical and research experience to begin a new chapter at the Wittlich clinic.
