About the Lab

Our laboratory currently specializes in the reward and reward-related learning processes that lead to nicotine and tobacco dependence. We are also interested in the reward-enhancing effects of psychomotor stimulants and how these can translate to higher rates of tobacco dependence in alcoholics and more binge drinking when caffeine and alcohol are consumed together.
