Dr. Seth Welles has worked for more than 14 years to understand the impact of HIV phenotypic and genotypic antiretroviral drug resistance on HIV disease progression and transmission. Dr. Welles also studies psychosocial risk for HIV infection and STDs among sexual minority adults and adolescents. He has conducted random surveys of sexual minority adults at community festivals and at health-clinics to assess demographic and psychosocial determinants of sexual risk-taking and HIV/STD infections and has recently developed Internet-based and audio-Computer-Assisted Interviewing (A-CASI) technologies for recruitment and data collection in sexual minority populations. He is committed to community-based participatory research and has a demonstrated interest in working with marginalized populations. Dr. Welles' research has been funded by both NIH and the CDC.
Dr. Welles has experience teaching epidemiology at all levels. He has led a number of different graduate epidemiology courses (at Boston University and University of Minnesota) and has advised and mentored many MPH and several doctoral students. At the Drexel School of Public Health, Dr. Welles will be continuing his research, developing advanced epidemiology course content in support of our new doctoral program, and advising our Epidemiology concentrators interested in HIV and infectious disease.
Research Interests: Viral epidemiology, including infection and pathogenesis; HIV/AIDS natural history; STI risk in sexual minority men of color; impact of childhood sexual abuse on various HIV/STI risk indicators.
Title: India Men’s Sexual Health Internet Study Funding: Cleveland State University and the University of Texas SPH Summary: Epidemiologic study to measure types and rates of sexual behaviors among non-gay identifying men who have sex with men who seek sex partners on the Internet throughout India. Additionally, we will measure several putative determinants of non-disclosure and high risk including racism, homophobia, and reduced self-efficacy. Role: Co-Investigator
Title: Program in Lesbian, Gay, Bisexual, and Transgender Public Health Research Funding: Boston University School of Public Health, 2004- Summary: Epidemiologic study to measure types and rates of sexual behaviors among African-American men seeking primary healthcare at several Boston Medical Center-affiliated walk-in clinics. In those men reporting same-sex behaviors, we will measure several putative determinants of non-disclosure and high risk including racism, homophobia, and reduced self-efficacy. Role: Director for Program
Title: Psychosexual Risk for HIV in African-American MSM—the Minority AIDS Research Initiative (MARI): PI: Anita Raj, PhD Funding: CDC, 10/01/03-9/30/06 Summary: Epidemiologic study to measure types and rates of sexual behaviors among African-American men seeking primary healthcare at several Boston Medical Center-affiliated walk-in clinics. In those men reporting same-sex behaviors, we will measure several putative determinants of non-disclosure and high risk including racism, homophobia, and reduced self-efficacy. Role: Co-Principal Investigator, mentor to Dr. Raj, junior investigator
