Research and Teaching Interests:

My main research interests center on understanding the brain mechanisms of decisions. Specifically, this involves exploring the impact of environmental factors that contribute to reward-related choice and the incorporation of costs in decision making. To that end, my lab studies the impact of drug exposure, development, diet, exercise, stress, and inflammation on these processes using a combination of behavioral, molecular, pharmacological, and computational methods. More recently we have investigated the role of uncertainty, risk, and reinforcement history on choice behavior. A better understanding of the basic mechanisms in reinforcement learning and choice behavior contributes to our knowledge of addictions, in particular.

Biography:

Dr. Izquierdo received a B.S. in Biology and Psychology from Emory University, and a Ph.D. in Cognitive Neuroscience through the Graduate Partnership Program between the National Institutes of Health and the George Washington University. After completing her doctoral work at the National Institute of Mental Health, she spent two years as a postdoctoral fellow at the National Institute on Alcohol Abuse and Alcoholism. Dr. Izquierdo received the Hispanic Association of Colleges and Universities Faculty Mentor award, and is active in a number of national organizations and initiatives that promote diversity in STEM. In 2016 she was selected as a Kavli Fellow of the National Academy of Sciences.
