Dr. Weir focuses on HIV prevention among people who inject drugs and other at-risk populations. His current HIV-related research includes needs assessment among Baltimore needle and syringe exchange clients and other people who inject drugs in Baltimore, effectiveness of pre-exposure prophylaxis among male sex workers in Thailand, and economic issues in HIV/AIDS prevention and treatment in Tanzania. An additional area of interest is using emergency medical services (EMS) data to describe the epidemiology of drug overdose, violent trauma, asthma, and other acute and chronic health conditions in Baltimore. He is a lead consultant with the Biostatistics, Epidemiology and Data Management Core at the Center for Child and Community Health. Previously, Dr. Weir conducted public health research on a variety of health issues within local and state health departments.
