My research is primarily focussed on how the information stored in age registering structures, such as shells and ear bones (otoliths), can be used to inform management of marine fisheries. Over the last 5 years I have worked on projects that utilized sclerochronology (the study of periodic growth rings in calcified structures) aiming to improve our understanding of several biological and ecological aspects of commercially important species. My PhD research focussed on the development of reliable ageing techniques for the common whelk, which supports important fisheries within the UK. This was achieved with a wide range of experimental and geochemical analyses to validate annual rings in statoliths (analogous to otoliths).
I began working with BAS as a post-doc investigating benthic community structure and Antarctic gastropods on the ICEBERGS project. I then started my current post as the fisheries ecologist, where I work on several aspects of the fisheries around the island of South Georgia. One of my main responsibilities is the Patagonian Toothfish ageing program at BAS, where I work closely with the Government of South Georgia & the South Sandwich Isles (GSGSSI), and the Centre for Environment, Fisheries and Aquaculture Science (CEFAS) to provide information for the long-term ecosystem based management of this species.
Since 2018, I have been a member of the UK delegation to CCAMLR, and have participated in the working group on stock assessment and management (WG-SAM) and the working group in fish stock assessment (WG-FSA).

This project assesses how climate change affects Patagonian and Antarctic toothfish populations in the South Atlantic. Led by British Antarctic Survey (BAS), it focuses on the UK Overseas Territory of South Georgia & the South Sandwich Islands.
Zooplankton are a vital part of the Scotia Sea food web. The project aims to improve the way we manage and monitor the pelagic ecosystem around South Georgia.
This project is improving our understanding of fish bycatch in the Antarctic krill fishery, to help support better management and conservation.
This project introduced fixed-wing drone surveys at South Georgia to monitor wildlife population changes driven by climate change and recovering seal, whale and finfish populations.
The shortlist has been announced for The Natural Environment Research Council’s (NERC) Impact Awards 2023. Four BAS projects have made the shortlist and commended list, ranging from biodiversity and ecology to space weather.
Next generation fixed-wing drones, capable of operating autonomously beyond the standard visual line of sight, are creating datasets of major wildlife populations around South Georgia for long-term monitoring to aid […]
A special issue of the journal Deep-Sea Research which includes contributions from British Antarctic Survey (BAS) scientists features a range of new research which increases our understanding of the understudied South Sandwich Islands.
King Edward Point Research Station on South Georgia is a centre for marine and fisheries research.
