Dr. Friedman's research focuses on individual differences in executive functions –– high-level cognitive abilities that enable individuals to regulate their thoughts and actions during goal-directed behavior. Dr. Friedman study the neural and genetic mechanisms of executive functions, their structure, and their relations to self-regulation, psychopathology, and other cognitive abilities.
