Research Summary

The goal of our laboratory is to develop more efficacious treatments for alcohol use disorders and nicotine dependence and to provide the science base for the regulation of tobacco products. Toward this end, we are conducting clinical trials to determine efficacy of medications and behavioral interventions, and laboratory studies to determine the mechanisms underlying the effects of treatment and the underlying nature of the disorder. Research on how flavors, such as methol and sweeteners, influence the use of tobacco products is underway to inform the regulation of tobacco products by the FDA.
