I am a quantitative marine ecologist with expertise in developing ecological models and empirical indicators to support an ecosystem approach to fisheries management. My recent research has been focussed on understanding and predicting the relative impacts of climate change and fishing on large marine ecosystems and fisheries around the world. Previously based at the University of Sheffield, I have taken up an Associate Professor in Ecology & Fisheries position at the Institute of Marine and Antarctic Studies at the University of Tasmania in Hobart where I will be primarily based whilst working on the project. I am deputy leader of Module 4 with Paul Blackwell and am an associated researcher at both the University of Sheffield and Imperial College London.
One of my current research interests is developing and testing marine ecosystem model ensembles, which I believe is needed to assess the uncertainty associated with model predictions. In addition to MERP model ensemble my ongoing global and regional scale modelling work is contributing to international multi-model comparisons (Inter-Sectoral Impact Model Intercomparison Project and IndiSEAS). These collaborations and a new Centre for Marine Socioecology at IMAS-CSIRO in Hobart will strengthen the international links within the project. I also have strong links with the Centre for Environment, Fisheries and Aquaculture Science CEFAS, Lowestoft, UK where I was a Senior Research Scientist and where I began my research on marine ecosystem dynamics and fisheries in 2001.
I was the coordinator of the ESF-funded 4 year research network SIZEMIC “Body Size and Ecosystem Dynamics: Integrating pure and applied approaches from terrestrial and aquatic ecology to support an ecosystems approach”, am a member of International Council for the Exploration of the Seas and NCEAS working groups, have lead research several European Union and UK Defra projects, and I am a contributor to the Marine Climate Change Impacts Partnership (MCCIP).
