James is broadly interested in the effects of environmental change on marine communities and the management of invasive species. His PhD is focused on characterising invasive lionfish (Pterois spp.) populations on Caribbean mesophotic coral ecosystems and determining their impact on native fish communities. To do this he will use prototype robots with the ability to reach depths beyond 200m, developed by RSE, to capture lionfish and conduct surveys of mesophotic communities. Using these data, James hopes to develop a spatially-structured demographic model to investigate lionfish population dynamics, explore different culling scenarios and develop hypotheses for optimal management strategies. James’ field work is primarily based at Operation Wallacea’s field sites in Honduras.
