I study how individuals make decisions. My research studies how adults make decisions about children and adolescent mental health and how to integrate tools to improve their decision-making. My research also examines frustration in children – what makes children more easily frustrated and what are the consequences in their thinking and decision-making.

Research Interests

Andrew Freeman is a child clinical psychologist who specializes in the etiology and assessment of irritability with a particular focus on the function of irritability in bipolar disorder and disruptive behavior disorders in children and adolescents. His research reflects and attempts to integrate two traditions in psychopathology: evidence-based medicine and developmental psychopathology. In terms of evidence-based medicine, Dr. Freeman's research focuses on developing and implementing clinically-friendly and actuarially sounds methods to improve the diagnosis of pediatric bipolar disorder and disruptive behavior disorders. In terms of developmental psychopathology, Dr. Freeman's research focuses on understanding the role of frustrative non-reward in pediatric mood disorders and its potential as a "common factor" between internalizing and externalizing disorders. His developmental psychopathology work is particularly interested in defining the boundaries and links among disruptive mood dysregulation disorder, oppositional defiant disorder, and bipolar disorder in children and adolescents.
