Based at the University of York, UK, my research has been focused on the structural biology of viral and bacterial nucleic acid binding proteins; and Staphylococcal cell surface adhesins and two-component sensors. I use methods including bioinformatics, structure prediction, molecular biology, bacterial recombinant protein expression and purification, X-ray crystallography, SEC-MALS, CD spectroscopy, small angle X-ray scattering, force unfolding AFM to determine the relationship between the structure and the function of target proteins. I recently relocated to the University of Adelaide where I have been developing the use of cryo electron microscopy in analysis of bacteriophage transcriptional regulators.

I am now using my expertise in protein engineering to develop a pipeline for directed evolution of novel small molecule sensors based on natural bacterial two-component sensor systems. The aim of this work is to select for new sensor/small molecule binding by building bacterial circuitry to select for sensor activation. This synthetic biology approach will provide the foundation for a 'biosensor' library able to specifically detect the presence of target molecules for deployment in diverse industries including medical diagnostics, food security, biomonitoring and bioremediation. This work is supported by the Ramsay Fellowship in Applied Science.
