My principle interest is in understanding the processes that govern patterns of biodiversity in the deep sea. In particular, I’m fascinated by how populations of deep-sea species are connected to each other and how processes over time can lead to divergence and eventually speciation. To this end, I work primarily with molecular genetic tools to understand patterns of population connectivity and demographics and to infer patterns of relatedness between species. At present I am working with animals associated with deep-water coral ecosystems on sea mounts to understand the vertical and horizontal scales of population connectivity and gene flow. Additionally, I work on the biogeography of animal communities at deep-sea hydrothermal vents. That is to say, I’m interested in trying to understand why different parts of the worlds oceans harbour different hydrothermal vent communities – so-called biogeographic provinces. In particular, I’m interested in how Yeti crabs, a family of chemosynthetically-associated squat lobster crustaceans, evolved over the last 40 million years, in order to understand the resilience of hydrothermal vent species to disturbance at various timescales. I’ve also recently studied the connectivity of species between hydrothermal vents in the Southern Ocean, which can be conceived of as biomass islands surrounded by the biomass ‘deserts’ of the deep sea.

RRS James Cook research Cruise 42 (Jan – Feb 2010)
Explored the East Scotia Ridge in the Atlantic sector of the Southern Ocean using ROV ISIS and retrieved, for the first time ever, hydrothermal vent animals from the only known vents in the Southern Ocean.
SERPENT Project, 2009
Flew out to oil drilling ships and rigs in the Norwegian sea and Faroe-Shetland channel and conducted deep-sea benthic surveys utilizing industry remotely operated vehicles (ROVs) as part of the SERPENT scheme (Scientific and Environmental Rov Partnership using Existing iNdustrial Technology).
Marine Mammal Observer 2005 – 2008
Worked as a Minerals Management Service (MMS) marine mammal observer on seismic survey vessels in the Gulf of Mexico, ensuring that seismic operations were halted in the presence of marine mammals. Totalled more than 1.5 years of at sea time.
