Andrew J. Freeman, PhD., is an assistant professor of psychology at the University of Nevada, Las Vegas. His research focuses on two areas. He examines how clinicians integrate information that they gather about an individual to make treatment decisions (e.g., provide a diagnosis, determine treatment options). He also examines how irritability might serve as a link between disruptive behavior disorders and mood disorders. He examines the underlying etiology of irritability and the best methods for assessing clinically significant irritability. Dr. Freeman has served as a consultant for statistical services and to organizations regarding the implementation of evidence-based practices. Dr. Freeman actively recruits graduate students to the clinical psychology PhD program, teaches undergraduate and graduate courses, and runs an active research lab at UNLV.
