Professional Summary:
Katelyn Carr, PhD, is an assistant professor in the Division of Behavioral Medicine, Department of Pediatrics. Her research centers on using experimental methods and behavioral economics to study decision making in children and adults to improve health choices. Her current research focuses on studying how choices influence the reinforcing value of food, including non-food alternative reinforcers. She also examines decision making in children, including delay discounting and how innovations in episodic future thinking can improve delayed choices.
