Seth Walker, PhD, BCBA-D is an Adjunct Assistant Professor in the Severe Behavior Department at the UNMC Munroe-Meyer Institute. Dr. Walker received his Master’s degree in special education with an emphasis in Applied Behavior Analysis from the University of Utah under the mentorship of Dr. Rob O’Neill. He received his PhD from Utah State University in Disabilities Disciplines: Applied Behavior Analysis under the mentorship of Dr. Tyra Sellers in 2020 while also serving as an Early Career Fellow at the Behavior Analyst Certification Board. The Severe Behavior Program clinics provide assessment and treatment to children with severe problem behaviors. The aim of services is to provide evidence-based behavioral assessment, intervention, and training to individuals and their caregivers, focusing on decreasing problematic and maladaptive behaviors and teaching functional, alternative behaviors using the principles of Applied Behavior Analysis.
Dr. Walker’s research interests involve increasing the safety and efficiency of assessment procedures for severe challenging behavior. Additionally, Dr. Walker is investigating applications of technology in behavior-analytic assessment and treatment approaches. His current investigations include applications of machine learning in behavior analysis, using virtual reality to increase compliance with activities of daily living, and developing software solutions for both research and practice applications.
