Courtney McKnight is a Clinical Assistant Professor in the Department of Epidemiology at New York University’s School of Global Public Health where she specializes in mixed methods research focused on the epidemiology of drug use, drug overdose, HIV and HCV infection. Dr. McKnight began her career in public health directing a harm reduction program for women who use drugs and volunteering at a syringe services program. Her research interests include examining changes in the unregulated drug supply, including the use of fentanyl and xylazine, and how these changes impact people who use drugs. She is PI on a CDUHR pilot project examining xylazine test strip use and HIV risk behaviors among a cohort of people who inject drugs in New York City, and a Co-Investigator on the DRIVE project, a community-based intervention study in Haiphong, Vietnam that identifies and links HIV positive people who inject drugs to HIV care through peer support to facilitate individual-level viral suppression with the over-arching goal of reducing population viral load and ending the HIV epidemic among PWID in Haiphong.
