The Analytic Core provides expertise and systems for the conduct and analysis of qualitative studies, pilot intervention studies, randomized controlled trials (RCTs) and economic studies. Led by Dr. Travis Sanchez and Dr. Kate Muessig, the Analytic Core works with the Technology and Management Cores to set up systems to manage participant recruitment and retention and ensure data quality and security. The Analytic Core supports cleaning and integration of multiple data sources (e.g. technology usage metrics – paradata, biological outcomes, surveys, costing data), conducts quantitative and qualitative primary analyses, and supports interpretation and dissemination of study results.
The Analytic Core is housed under PRISM Health (Programs, Research, & Innovation in Sexual Minority Health), which is based within the Rollins School of Public Health at Emory University. PRISM Health conducts a broad portfolio of National Institutes of Health (NIH), US Centers for Disease Control and Prevention (CDC), and foundation-funded studies and projects and actively collaborates with community-based organizations to conduct research, to generate theories and knowledge, and to translate findings into effective sexual health interventions and programs.
Kate Muessig, PhD
Co-Director Analytic Core
Kate Muessig is an Assistant Professor and health behavior interventionist at the University of North Carolina at Chapel Hill Gillings School of Global Public Health. She uses mixed-methods research to develop and evaluate technology-based interventions with youth, particularly men who have sex with men and transgender individuals, to support HIV prevention and care. Dr. Muessig co-leads a mixed methods study analyzing online forum data to understand the potential for online stigma-reduction interventions for young Black men who have sex with men (R21MH105292). She has also led the qualitative components of two completed (HealthMpowerment.org and Tough Talks) and three ongoing (Epic Allies, Ally Quest, Test Rehearsal) NIH-funded eHealth interventions. She is co-Director of the Analytic Core of the iTech. In this role, she supports the development and implementation of the formative and pilot phases of all iTech studies.
Travis Sanchez, DVM, MPH
Co-Director Analytic Core
Dr. Travis Sanchez graduated with a Doctor of Veterinary Medicine from University of Georgia in 1994 and a Master of Public Health from Emory University in 2000. He has extensive experience in infectious disease epidemiology, including HIV epidemiology and prevention in the United States at the local, state, and federal levels. He worked as an epidemiologist in Fulton County and then coordinated Georgia’s District Epidemiology program. He worked at the Centers for Disease Control and Prevention for 10 years and helped to establish 2 supplemental HIV surveillance systems – the National HIV Behavioral Surveillance System and the Medical Monitoring Project. He led two of CDC’s first research studies on risk factors for HIV infection among transgender persons and created a new CDC system for conducting HIV behavioral surveillance with MSM using entirely online research methods. Dr. Sanchez was associate chief for science for 2 CDC branches within the Division of HIV/AIDS Prevention and was the strategic information branch chief for CDC-South Africa. He is currently the principal investigator of the American Men’s Internet Survey, an annual online behavioral survey of US MSM 15 years of age and older. This survey has collected more than 50,000 surveys from MSM in every US state over the past 5 years. Dr. Sanchez’s other current studies also include a wide breadth of HIV research and program that is relevant to the Adolescent Trials Network – at-home HIV testing, HIV pre-exposure prophylaxis, tech-based HIV prevention, tech-based HIV care support, and online data collection.
