I graduated in Zoology from Cambridge University in 1990 and undertook my PhD in intertidal ecology at Port Erin Marine Laboratory, on the Isle of Man between 1991 and 1995. I remained at Port Erin for a further 6 years, undertaking two post-doctoral research posts, the first, within the EUROROCK project, addressing ecological questions on intertidal rocky shores over a European scale and the second, examining the impacts of demersal fishing techniques on benthic communities. In 2001 I was appointed a Research Fellow at the Marine Biological Association where I developed a research group in experimental benthic ecology. In 2007 I moved to the School of Ocean Sciences, in 2009 was appointed Reader in Marine Ecology and was awarded a personal chair in 2015.
I am an experimental benthic ecologist and over the past 25 years I have addressed questions in both fundamental and applied ecology in intertidal and shallow sub-littoral habitats. Particular areas of interest include: the transport, supply and recruitment dynamics of benthic invertebrate larvae; the role of ecosystem engineers and key herbivores in intertidal systems and the generality of their effects over large geographic scales; the role of biodiversity in marine systems; the ecology of non native species and practical biosecurity interventions; anthropogenic impacts in the marine environment. I take an empirical approach using a combination of field / mesocosm experiments and long term surveys.
