My work focuses on HIV and STI prevention and care with disadvantaged populations, mental health and distress among inner-city residents, the role of substance abuse on HIV risk behaviors, and measurement of social-contextual factors including social and personal network analysis, neighborhood characteristics, and geographic information systems among disadvantaged populations. I have helped design, implement, and evaluate over a dozen randomized clinical trials of behavioral social network oriented interventions for disadvantaged populations.
