Mikhail Koffarnus, Ph.D.
Research Assistant Professor
Dr. Koffarnus's research focuses on understanding drug abuse and developing drug abuse treatments from behavioral economic and pharmacological perspectives. Decision-making processes are often disrupted in drug users, leading to a systematic preference for immediately available rewards like drugs over delayed rewards like improved health or gainful employment. One of the areas he studies involves how these impulsive versus self-controlled choices are involved in drug abuse and whether modifying these decision-making patterns can improve drug abuse treatment prospects. Additionally, he is interested in these same decision-making patterns that underlie other problematic health behavior such as overeating.
