I am an ecologist researching invasive species and their impacts on native plants and ecosystem functioning. I am interested in understanding what makes plants invasive and how invasive plant species can be best controlled. I joined the UK Overseas Territories team in December 2014 and am working on conservation projects in South Georgia and the South Sandwich Islands as well as the British Virgin Islands. My PhD student, Adam Devenish, successfully defended his thesis in February 2019, which assessed the impacts of the invasive Argentine ant, Linepithema humile, on native ants and seed dispersal processes in both Spain and South Africa. I have a strong background in seed ecology in species from the fynbos and temperate woodland ecosystems.
