Biography 

My research is focused in two main areas: (i) understanding the pathogenic mechanisms and underlying biology of the global pathogen Mycobacterium tuberculosis; and (ii) discovering and developing novel drugs that are effective at curing drug sensitive and drug resistant tuberculosis.

Current translational work within my group encompasses a range of early stage drug discovery including drug target identification and validation, high throughput screening and medicinal chemistry. My applied research has covered a broad range of chemistry and biology as applied to drug discovery from high throughput screening through to lead optimization. My current fundamental research addresses mechanisms of antibiotic resistance, the mode of action of antibiotics and the investigation of essential cellular processes in mycobacteria. I also have an interest in gene regulation in mycobacteria and cell wall biosynthesis pathways. In addition, using M. tuberculosis as a paradigm, I seek to understand the mechanisms by which antimicrobials ultimately cause cell death.
