BIO
Holly Hagan trained as an infectious disease epidemiologist with an emphasis on methods to study disease causation and control. Her research has addressed the etiology, epidemiology, natural history, prevention and treatment of blood-borne and sexually transmitted infections in key populations in general and among people who use drugs (PWUD) in particular. She is skilled in research synthesis (systematic reviews and meta-analyses) and the methods of implementation science. She has designed and led a number of large observational and experimental studies related to blood-borne viral infections in PWUD, men who have sex with men (MSM), and heterosexuals at high risk of HIV. Dr. Hagan is a member of the WHO Global Burden of Disease Study Diseases and Injuries Group, she served on the Institute of Medicine Committee on the Prevention and Control of Viral Hepatitis in the United States, and have been an advisor to the US Department of Health and Human Services, the CDC, and the Canadian Institutes of Health on national programs to detect, diagnose and treat HCV infections.
