Professor Emeritus

Dr. Holly Hagan is Professor Emeritus at the School of Global Public Health. Trained as an infectious disease epidemiologist, Dr. Hagan’s work has sought to understand the causes and consequences of substance use disorders. Her research has examined blood-borne and sexually-transmitted infections among people who use drugs. She is an internationally-recognized expert in the etiology, epidemiology, natural history, prevention and treatment of hepatitis C virus infection among PWUD, and in 2014 her work was recognized by the US Department of Health and Human Services with the President’s Award for Leadership in the Control of Viral Hepatitis in the United States. Dr. Hagan served on the Institute of Medicine Committee on the Prevention and Control of Viral Hepatitis in the United States, and she has 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. She was recently appointed to the National Academy of Medicine Committee on the Examination of the Integration of Opioid and Infectious Disease Prevention Efforts in Select Programs.

Dr. Hagan is the Director of the NIDA P30 Center for Drug Use and HIV|HCV Research at Global Public Health, which provides research support to investigators throughout NYU and in two other NYC institutions. In 2017, she was selected by NIDA to chair the Executive Steering Committee for the Rural Opioid Initiative funded by NIH, CDC, SAMHSA and the Appalachian Regional Commission. Her research has shifted to examining the impact of the opioid crisis more broadly, to include studying the epidemiology of fatal and non-fatal overdose among PWUD. She was chosen by the American Foundation for AIDS Research to be the Principal Investigator for the New York State Opioid Prevention Center pilot study, which will examine the safety and effectiveness of the Supervised Consumption Sites to be implemented in New York City and in upstate NY.
