The focus of our work is the development and evaluation of new diagnostic tests for tuberculosis (TB). There is an urgent need for sensitive, specific, rapid tests for detection of active TB disease, latent TB infection, and M. tuberculosis drug resistance.

Our TB diagnostics work involves both laboratory and clinical research, and we have active collaborations with investigators in Brazil and Honduras. The other major focus of our work is the investigation of immunologic and genetic factors that affect susceptibility to M. tuberculosis.
