Denys Brand, Ph.D

Assistant Professor

Department of Psychology

California State University, Sacramento

6000 J. Street

Sacramento, CA 95919-6007 

Dr. Denys Brand is the director of the Performance Improvement Laboratory and an Assistant Professor in the Department of Psychology at California State University, Sacramento.  He was awarded his PhD in psychology from the University of Auckland (New Zealand) in 2015.  His doctoral dissertation was supervised by Drs. Oliver Mudford and Douglas Elliffe, and involved using sequential analysis (specifically, markov probability chains) to identify problematic sequential dependencies affecting the treatment integrity of discrete-trial teaching programs for children with disabilities.  Following his PhD, he worked three years as a post-doctoral researcher at the University of Kansas under the supervision of Dr. Florence D. DiGennaro Reed. Dr. Brand has published in peer-reviewed academic journals, including the Journal of Applied Behavior Analysis, Journal of Organizational Behavior ManagementJournal of Behavioral Education, Behavior Analysis in Practice, Behavioral Interventions, Teaching Exceptional Children, and European Journal of Behavior Analysis. He currently serves on the editorial boards for Journal of Organizational Behavior Management, Journal of Applied Behavior Analysis, and European Journal of Behavior Analysis. Additionally, he is a former board member for the Mid-American Association for Behavior Analysis and currently serves on the OBM Network Research and Education Committee. Presently, his research interests include performance feedback, procedural integrity, and preference assessments in the workplace. Dr. Brand is passionate about the study of behavior in both experimental and applied settings and enjoys working alongside undergraduate and graduate students as a teacher and researcher.
