My research interests include the design, conduct, and analysis of HIV-related clinical trials and the analysis of longitudinal cohort data related to AIDS comorbidity research. I am a biostatistician for projects to detect, prevent and treat cryptococcal meningitis and TB meningitis in Uganda, South Africa and Indonesia.
