Research Interests

Tuberculosis (TB) accounts for 2 million deaths worldwide. After infection with M. tuberculosis (the etiology pathogen of tuberculosis), humans can either contain the infection or develop active disease.  Our lab is focused on the host protective immune responses to M. tuberculosis, a major factor in outcome of infection. We are also interested in the interaction between SIV-Mtb co-infection, especially in the context of the global epidemic. We are able to simulate both M. tuberculosis infection and SIV-Mtb co-infection in animal models and follow disease progression using in vivo PET-CT imaging. Our current studies involve identifying immunologic causes and bacterial sources of reactivation TB and relapse after treatment.
