I am a marine ecologist and taxonomist working on the biodiversity of cold-water coral reefs formed by the colonial scleractinian Lophelia pertusa and the marine benthic Hydrozoa (hydroids).
My research adopts a multidisciplinary approach to studying cold-water coral reefs. Spatially explicit models of biodiversity are derived across multiple spatial scales using environmental data acquired from multibeam bathymetry, benthic lander platforms and imagery, and species data.
Deep-sea sampling provides an abundance of hydroids, which I have found are richly represented in cold-water coral habitats on the Darwin Mounds, Belgica Mounds, Mingulay Reef Complex, and off the southeastern US and Bahamas. Currently I am working on an Atlantic basin-scale analysis of the biodiversity and biogeography of the hydroid fauna associated with Lophelia to elucidate connectivity patterns and the role of large-scale forcing factors.

I did a B.Sc. Honours with the Department of Biology at the University of Ottawa in Canada in 1998. My thesis project was to quantify patterns in the aquatic macrobenthic communities inhabiting streams in the Ottawa-Hull region. Species richness and composition of these lotic invertebrates were significantly related to aquatic chloride concentration, which is largely derived from rock salt used to safeguard vehicles in the extreme winter climates of Ottawa.
I proceeded to a M.Sc. degree in Zoology with the Department of Zoology at the University in Toronto in Canada in 2000, in conjunction with the Department of Invertebrate Zoology at the Royal Ontario Museum in Toronto. I examined the rich biodiversity of the hydroid fauna inhabiting the Passamaquoddy Region of the Bay of Fundy, and the seasonality and ecology of the intertidal hydroid Dynamena pumila. This species is quite a robust beast, surviving a wind chill of -20°C and shearing ice flow in the winter, and intense reflecting sunlight and humidity up to 30°C in the summer. I also established a taxonomic consultancy with the Smithsonian Environmental Research Center in the US to identify hydroids as part of the Smithsonian’s successful international invasive species programme, a collaboration that I maintain today.
My Ph.D. in Biology with Dalhousie University in Canada in conjunction with the Department of Fisheries and Oceans at the Bedford Institute of Oceanography examined the effects of bottom fishing on the biodiversity, distribution and life history aspects of sessile benthic communities in the Canadian maritimes. I am also became a charter member for the Canadian Centre for Marine Biodiversity, a virtual centre for various stakeholders of Canada’s three oceans.
My Ph.D. research initiated my sustained interest in the biodiversity associated with cold-water corals, and lead to an EC-funded Marie Curie post-doctoral fellowship at the Scottish Association for Marine Science in Oban. Today I continue this research at the Centre for Marine Biodiversity and Biotechnology at Heriot-Watt University in Edinburgh and participate on the ICES Working Group on Deep-Water Ecology.
