About

Biological membranes differentiate our cells from the extracellular environment and micro-organisms that cause disease. Essential to the function of these bio-membranes are the protein molecules embedded within them. My research uses X-ray crystallography and Cryo-Electron Microscopy to visualise these membrane proteins in near-atomic detail to understand how they function in the context of health and disease. For example, how does a resistance transporter protein transport particular drugs selectively? How does a receptor recognise a specific molecule and turn this into a signal affecting cell behaviour? Visualising the structure of these proteins in complex with the molecules they interact with is often a necessary first step in understanding these phenomena for developing treatments and technologies that can benefit society.

I have recently become increasingly interested in using synthetic biology to engineer the membrane proteins within yeast for a particular purpose,  including the creation of living bio-sensors for disease diagnosis, displaying a synthetic library of "nanobodies" on their surface  and modifying the secretory pathway for high-yield production of valuable proteins.

Yeast fermentation is a multi-billion dollar global industry, at the basis of many new Synthetic Biology companies. A key aspect of this technology is being able to efficiently excrete high value protein products from the yeast cells which significantly simplifies downstream purification.

The best treatment for Malaria is currently via the combination of the drugs Artemisin and Piperaquine, but emerging resistance to both of these front-line antimalarial drugs means there is an urgent need for new treatment options and a better understanding of resistance mechanisms.

The cells of our organs must form tight barriers with each other in order to differentiate themselves and perform their function. These cellular junctions and attachments display exquisite mechanical and chemical sensitivity that if perturbed, often leads to disease states within the body.
