Tony W. Buchanan, Ph.D.

Professor, Experimental Program: Cognition & Neuroscience; Co-Director of Neuroscience Program
Department of Psychology


Ph.D., University of Oklahoma

Research Interests

My research focuses on the relationships between stress and behavior. My work focuses on two related, but distinct questions: 1) How does stress impact cognition, especially decision making? And 2) How does stress impact the physiology and behavior of addiction, specifically gambling disorder and substance use disorder?
