Description of Research Expertise

HIV clinical epidemiology; outcomes of HIV treatment; adherence to therapy including development of methods to measure adherence

Description of Itmat Expertise

Dr. Gross focuses on antiretroviral therapy for HIV with a primary focus on the relation between adherence to therapy and outcome and barriers to adherence and interventions to overcome barriers to adherence. He also conducts research on new antiretroviral agents as well as pharmacoepidemiology and pharmacogenetics of HIV drugs.
