Research Focus

My research focuses on tuberculosis. It is a major threat to human health, with 9 million new cases and 1.5 million deaths every year. I have focused my career on improving tuberculosis diagnosis and care, with research that includes evaluating diagnostics tests that could eventually be part of country-level policies, implementation of tools and policies, and improving tuberculosis care for vulnerable populations in different countries worldwide. For example, I have compared the accuracy and usefulness of new tests that can diagnose tuberculosis in a few hours to conventional techniques which may require days before results are known. I am also conducting a study using mystery patients to evaluate the quality of tuberculosis care offered by health providers in India. The overall goal of my research program is to use translational epidemiology and implementation science to support tuberculosis care and control, so that the products developed, knowledge and policies can translate into saved lives.
