Epidemiology and Biostatistics
United States of America
"Dr. Welles received doctoral training in both cellular/molecular epidemiology at Boston University and viral epidemiology at the Harvard School of Public Health. He conducts research and mentors students in studies of infection and chronic disease, including viral carcinogenesis and HIV/AIDS. His earliest epidemiologic work was focused on studies of immune suppression and adult T-cell leukemia/lymphoma caused by the human T-cell lymphotropic virus type I (HTLV-I). Subsequently, he worked as an epidemiologist and biostatistician with the AIDS Clinical Trials Group to assess the utility of using molecular markers of HIV antiretroviral drug resistance, HIV-1 viral load, and CD4 cell number as prognostic and surrogate markers of clinical disease.
