Dr. Bangsberg's research focuses on HIV in impoverished populations. In 1996, he launched a series of studies in HIV+ homeless and marginally housed individuals in response to concerns that poor adherence to HIV antiretroviral treatment in the urban poor would create new strains of drug resistant virus. He described the challenges in providing antiretroviral therapy to the urban poor, developed valid measures of adherence, defined the risk of antiretroviral resistance by level of adherence, and developed effective interventions to improve adherence in the HIV+ urban poor. These studies mitigated what we now recognize were exaggerated concerns regarding HIV drug resistance in the urban poor and helped shift the debate from withholding treatment to maximizing treatment effectiveness.
