- Epidemiologic studies of infectious disease transmission
- Vaccine studies
- Development of novel statistical methods and designs for studies of infectious disease transmission
- Efficacy and effectiveness assessments of control and prevention strategies for infectious diseases of import to global health, including influenza, cholera, dengue, and tuberculosis
- Implementation and analysis of a cluster-randomized clinical trial of influenza vaccination among 6-month to 10 year-olds in rural Senegal, with the aim of estimating total, direct, and indirect effects of the vaccine, as well as characterizing the epidemiology of influenza in sub-Saharan West Africa. In addition, a transmission study was embedded within this trial.
- Estimation of the transmission potential of endemic cholera within a longitudinally-followed cohort of households in urban Bangladesh; the magnitude of the within-household transmission potential is compared to the risk infection from environmental sources of exposure.
- Estimation of the serotype-specific hazard of infection for all four serotypes of the dengue virus, using data from cohort studies in Nicaragua, Thailand, and elsewhere.
- Design of the phase IV dengue vaccine studies
- Development of novel statistical methods and study designs to extract more information about infectious disease transmission from outbreak investigations
- A novel software for analyzing the transmission of an infection within clusters of cases is being integrated into the field epidemiologic response capabilities of federal and local public health agencies
- Spatial epidemiology, advanced methods for the analysis of infectious disease transmission
- Supervising students
