Current area of research   :  Cellular and molecular biology
                           of mycobacteria; innate immunity

Specific  interests:

a.       Understanding proteins/enzymes of the cell wall biosynthesis and cell division machinery of mycobacteria at the structural and functional level as an approach towards developing agents for antimycobacterial chemotherapy.

b.       Understanding the stress response of mycobacteria at the system level.

c.       Dissecting mechanisms of mycobacterial pathogenesis.

d.       Global profiling approaches to understand how pathogenic mycobacteria regulate the innate immune response at the system level.
