Thanh C. Bui, MD, DrPH, is an Assistant Professor in the Department of Family and Preventive Medicine, and a member of the Stephenson Cancer Center. Dr. Bui has an interdisciplinary background in medicine, global health, health promotion research and cancer prevention research. Dr. Bui's main research interest focuses on behavioral interventions for cancer prevention and control in high-risk populations, including immunizations against oncogenic viruses and tobacco cessation.
His current NCI-funded research projects use mobile health (mHealth) technology to help vulnerable patient populations quit smoking cigarettes in the United States, in Cambodia, and in Lao People's Democratic Republic. Two other studies examine the relationships between tobacco use, marijuana use, oncogenic (co)infections, and several health outcomes among Americans. Other research interests of Dr. Bui include sexual health promotion to prevent cancers (e.g., HPV vaccination) and the application of innovation generation tools to promoting cancer prevention behaviors.
He has extensive experience in working with vulnerable high-risk populations, such as people living with HIV/AIDS, sex workers, and people with low socioeconomic status. He also has strong partnerships with senior investigators and health practitioners in developing countries in Southeast Asia, such as Vietnam, Lao PDR and Cambodia.

Ending Tobacco Use through Interactive Tailored Messaging for Cambodian People Living with HIV/AIDS (EndIT).
This research project aims to evaluate efficacy and cost-effectiveness of our theoretically and empirically based mobile health (mHealth) smoking cessation intervention for smokers living with HIV in Cambodia. This mHealth approach includes a fully automated, interactive, personalized, smartphone-delivered intervention for behavioral treatment.

Relational Agents in HPV Vaccine Education
This project aims to explore the efficacy of a computerized simulated interactable healthcare provider in educating survivors of an HPV related disease (e.g., cervical cancer) about the importance of HPV vaccination and engaging them in promoting HPV vaccination. Study sites include the NCI-designated Stephenson Cancer Center at the University of Oklahoma Health Sciences Center and the Karmanos Cancer Institute (KCI) at Wayne State University.
