I am a lecturer in the School of Ocean Sciences, specialising in the field of marine fisheries. For my PhD I studied the ecology and fisheries of the whelk, Buccinum undatum. This project developed age determination methods for this species using a wide range of approaches from aquarium-based growth experiments to advanced geochemical techniques that were used to reconstruct the life history of individual animals. These ageing tools are now in use across several fisheries for this species. 

From June 2018 to December 2023, I worked as a fisheries ecologist at the British Antarctic survey, researching a wide array of topics related to the fisheries around the island of South Georgia in the South Atlantic. Recently I have led projects investigating ecological aspects of commercially exploited fish species, improving bycatch reporting in the Antarctic krill fishery, and utilising fixed-wing drones to monitor key populations of penguins and seals. I have wide research interests broadly centred around the development and implementation of the ecosystem-based approach to fisheries management. I also use sclerochronology and geochemistry to improve fisheries management and elucidate connectivity and life histories of fish and molluscs.
