Research summary

I'm fascinated by evolutionary processes as a whole, at both organismal and molecular levels. In particular I'm interested in how environmental variability due to geography, climate and nutrient availability can lead to adaptation and diversification.

My current research interests lie with the cyanobacteria, photosynthetic microorganisms that are a fundamental component of the earth system. Cyanobacteria are key players in both the carbon and nitrogen cycles and are presumed responsible for the initial oxygenation of the earth's atmosphere.

During my PhD I'll be carrying out a comprehensive evolutionary study of cyanobacteria adapted to living in cold environments ...

After a first year studying Microbiology at the University of Leeds, I completed my undergraduate degree in Ecology and Environmental Biology (First Class Honours), specialising during my research project in evolution and population genetics. Between my undergraduate and masters programmes, I recieved scholarship to attend the Microbial Oceanography summer school at the Bermuda Institute of Ocean Science and worked as a teaching assistant on University of London undergraduate modules in Marine Biology and Microbiology. I joined the University of Southampton for my MRes where I was based at the National Oceanography Centre researching molecular mechanisms of acclimation to nutrient limitation ...
