Research Interests

We are focusedon the proteins involved in pathogen infection and drug resistance. We are studying on the Type 7 Secretion System (T7SS) in Mycobacterium tuberculosis and the effector proteins secreted by T7SS. We are also studying on the molecular mechanisms of the drug resistance in M. tuberculosis and other pathogens and the structureof the potential drug targets. As well, we are interesting in the regulation mechanism of the bacteria movement.
