My research focuses on the epidemiology of tuberculosis in South Africa, Brazil, India and the US, with specific focus on the drivers of TB in these settings. I am currently leading a cluster randomized trial in South Africa observing diagnostic and treatment practices for latent TB infection among HIV-infected patients at 14 HIV clinics. Also, in South Africa, I lead a smoking cessation clinical trial among HIV-infected patients and projects investigating indoor air pollution, smoking, and potential mHealth solutions for many patient populations. I also lead a study investigating TB treatment outcomes among TB patients with diabetes in India, and other studies in India looking at impact of indoor air pollution and smoking on TB in this setting.
In Brazil, we recently completed an 11 year Fogarty training program which has trained over 100 clinicians and public health researchers throughout Brazil, and has also included trainees from Mozambique, India and South Africa. As part of this program, I developed a one-year training course for clinicians and researchers emphasizing methods in developing, implementing and analyzing HIV/TB related epidemiologic studies. Also in Brazil, I co-led the THRio study, a cluster randomized trial in 29 HIV clinic throughout Rio de Janeiro, which showed that TB incidence can be reduced with proper implementation of TST and IPT. The data accumulated from THRio continue to fuel multiple analyses of the HIV/TB epidemic in Brazil, a country representative of middle income countries with a moderate TB epidemic.
In addition to the Fogarty training program, my interest in teaching extends to the Bloomberg School of Public Health where I am the primary instructor for the “Epidemiologic Basis for TB Control”, a course created by Dr. George Comstock over 50 years ago. This course is conducted twice-yearly, both in class and online as part of the distance education program at Johns Hopkins University.
