Research Focus

My broad research interests are in various aspects of tuberculosis, including epidemiology, genetic epidemiology, and best practices. I am particularly interested in the role of genetic variation in innate immunity pathways and susceptibility to different TB phenotypes. At present, I hold grants to prospectively investigate the role of human genetic variation in susceptibility to latent TB infection in a Seattle cohort and TB disease in a pediatric South African cohort.

I am interested in clinical studies in low resource settings. I am PI on a study of the prevalence of active TB among HIV-1-infected pregnant women in western Kenya and cofactors associated with TB disease and latent infection. Finally, I am involved in collaborative systematic reviews that are used to inform WHO guidelines on the management and diagnosis of TB. My scientific investigations are enhanced by my work as a clinician in the TB Control Program, Seattle & King County Public Health.
