Research Interests:
Social and spatial interactions in ecology
My research seeks to use electronic tracking devices and network analyses of animal movements to understand connectivity and grouping behaviour in ecological communities. Aggregation, collective movement and social interactions, often very difficult to measure in wild animals, can fundamentally impact the persistence and vulnerability of a species, so understanding the mechanisms behind such behaviour is crucial to mitigate against threats and inform management decisions.
I have a particular interest in the marine environment where often basic ecological knowledge of species or systems is hard to obtain. I believe tracking technologies, in combination with increasingly sophisticated spatial and temporal modelling techniques, can be applied to aid the monitoring and enforcement of highly dynamic and sometimes heavily exploited marine organisms. Specifically, I am interested in the dynamics and drivers of social networks in marine predators such as sharks and currently run projects in the British Indian Ocean Territory (BIOT) on reef sharks and the Canary Islands, on Angelsharks.
Freshwater eel conservation
Freshwater eels are heavily theratened at the global scale by multiple perturbations, yet have a long and complex life history that make them a real challenge to conserve. I have a keen interest in freshwater eel ecology and conservation and am currently the Red List Authority Coordinator for the IUCN Anguillid Eel Specialist Group following our full IUCN Red List assessment of the anguillid species in 2014.
