Our Team

The Project Quit team at the Medical University of South Carolina (MUSC) is dedicated to improving treatment for smokers who are trying to kick the habit. Our team is comprised of committed and focused researchers with varied backgrounds, including psychiatrists, psychologists, medical doctors, physician assistants, biostatisticians, and research support personnel of study coordinators and research assistants. The group is based out of the Addiction Sciences Division of the Department of Psychiatry and Behavioral Science and works collaboratively with the other campus research groups like the South Carolina Tobacco Research Group (SCTRIG).

Initially established to focus on a quit smoking study to assist adolescents, the Project Quit team has expanded to include other active research—both treatment based and observational—to better understand tobacco use disorder. The focus of the team is to explore the potential to improve treatment outcomes through the spectrum of tobacco users from adolescence through adulthood.
