Principal Scientist and Lead Advisor for climate change at Cefas (the UK government marine science agency based in Lowestoft, England). This role includes strategic planning of research goals and initiatives, as well as managing a ‘Memorandum of Understanding’ with the UK Department for Environment, Food & Rural Affairs (Defra) to provide advice and evidence on marine climate change. Director of the International Marine Climate Change Centre (iMC³) at Cefas. Honorary Reader in the School of Environmental Sciences at UEA, and Director of the Collaborative Centre for Sustainable Use of the Seas (CCSUS), a joint initiative between the UEA and Cefas that aims to to combine innovative science and practical expertise to achieve sustainable use of the oceans. 

25 years experience working in marine and freshwater ecosystems around the world, lead author of the UN Intergovernmental panel on Climate Change (IPCC) 6th Assessment report, ‘small islands’ chapter.  In-depth knowledge and practical experience in the assessment and modelling of fisheries, ecosystems and marine food-webs. Extensive experience in the administration and management of fisheries and climate change research programmes. UK delegate on the Science Committee of ICES (the International Council for the Exploration of the Seas) and was previously (until 2019) a co-chair of the ICES/PICES Strategic Initiative on Climate Change in Marine Ecosystems that aims to coordinate research activities across the North Atlantic and North Pacific oceans.

Research interests include: future scenarios (climate and socio-political), climate impacts in Small Island Developing States (SIDs), climate change risk and vulnerability assessment techniques.
