Dr Kerstin Williams

Research Fellow


Research interests

My general research interests are focused on applying molecular biology techniques to investigate Mycobacterium tuberculosis pathogenesis. Specifically, the identification of essential metabolic pathways and a more complete understanding of how mycobacteria detect and respond to their environment may identify novel drug targets to treat tuberculosis, the cause of 1.4 million deaths worldwide in 2012.

More specifically, my research interests are aimed at understanding nitrogen metabolism in M. tuberculosis. Nitrogen is an essential element for bacterial growth yet the nitrogen sources available to M. tuberculosis in vivo and the metabolic pathways used by the pathogen to assimilate nitrogen and survive in the host are unknown. A more comprehensive understanding of these essential processes could help identify novel drug targets to treat tuberculosis.
