Senior Health Analyst

William Zule, DrPH, is a senior research health analyst who joined RTI in 1999. He has been involved in community-based HIV and hepatitis C virus epidemiology and prevention studies since 1989. Dr. Zule’s early work helped clarify the context of indirect sharing in HIV risk among injecting drug users (IDUs). Other work has called attention to the potential impact of syringe type on HIV and HCV transmission among IDUs and to HIV risks among methamphetamine users. He has also published a series of papers examining and assessing treatment readiness and entry among out-of-treatment drug users.
