Research Interests

My research interests focus around membrane proteins and the lipid membranes in which they reside. I have experience of working with a range of membrane protein systems including receptors such as GPCRs, transporters and biogenesis systems. I use model lipid membranes to study proteins in their native environments and also to probe the effects of various compounds on the integrity of the membrane itself. For example, I have investigated the lipid-specific effects of antimicrobials and solvent on biological membranes. I have an ongoing collaboration with Green Biologics Ltd.

I am keen to collaborate on industrially-focussed projects as well as academic ones. Please get in touch if you would like to know more.

Scientific Inspiration

They aren’t particularly famous but I am a big fan of Seymour Jonathan Singer and Garth L. Nicolson who developed what is known as the “fluid mosaic” model of cell membranes. They were the first to really propose how cell membranes function in the manner we understand them today and this underpins nearly all of the work in my lab.

Project Outline

The global economy has an unsustainable dependence on fossil raw material and concerns about environmental sustainability are becoming more acute. Biotechnological processes using microorganisms as cell factories to produce valuable compounds from renewable biomass are an attractive alternative, and an increasing number of platform and high-value chemicals are being produced at industrial scale using this strategy. However, many microbial processes are not implemented at industrial level because the product yield is poorer and more expensive than achieved by chemical synthesis.

It is well-established that microbes show stress responses during bioprocessing and one reason for poor product output from cell factories is production conditions that are ultimately toxic to the cells, often at the level of the cell membrane. Examples of stresses that are demonstrably membrane-centric are solvents, e.g. butanol production by Clostridia and ethanol production by yeast, and weak acids such a lactic acid produced by bacteria. This project will seek to alter the cell membrane of industrial microbes to increase tolerance to stresses during bioprocessing.

Building on our recent findings in yeast and bacteria, the approach will use a powerful combination of in vitro assays, microbial cell culture, and ‘omics technologies to identify the molecular targets e.g. lipids and transporters. Genetic engineering to create strains will be followed by strain characterisation to determine if the desired membrane alterations have been achieved and if tolerance to a particular stress (or stresses) has been increased. Iterative design-build cycles will be undertaken as appropriate to further improve the strains.

This project would suit applicants with an interest in biophysics and biochemistry of the cell membrane and/or in microbial fermentations and industrial application of fundamental science.
