I am a Research Fellow at the University and I study coral populations across a broad depth range, from shallow, tropical coral reefs (<30 m), to the relatively unexplored mesophotic coral ecosystems (30-200 m), and beyond to the cold-water corals of the deep sea (>200 m). I am particularly interested in variation in diversity and community structure along the depth gradient, and the horizontal and vertical connectivity of populations via larval dispersal, and the implications of this on conservation and management of the marine environment. Currently, I am working on two key projects. I am investigating the changes in diversity and distribution of mesophotic reefs in the British Indian Ocean Territory in relation to depth and oceanographic drivers. In this project, I will assess the genetic connectivity of sessile reef species across the depth gradient from shallow to mesophotic depths to determine the potential of mesophotic reefs to resupply shallow reefs with larvae following mortality. In the second project (DeepLinks), we are investigating how patterns of population connectivity vary with depth in the deep sea, and how this influences species diversity, using a combination of molecular techniques, modelling and community analysis.
