Research Interests:

Pathogens secrete a variety of macromolecules to survive within their host which manipulate the immunological response of the host in order to facilitate survival and proliferation of the pathogen. My work focuses primarily on the genus Mycobacterium, specifically M. tuberculosis, the causative agent of Tuberculosis. The main objective of this research is to understand the complex immunological host–pathogen interactions and the course of Tuberculosis by (1) elucidating the biochemical mechanisms by which Mtb proteins are involved in host signal transduction pathways, and (2) elucidating the means by which this interaction contributes to the survival and the establishment of a successful infection within the host. It is expected that the information obtained from these studies will suggest new therapeutic approaches and new targets to control bacterial infections.
