We work on balancing the conservation of marine ecosystems with human uses of the oceans. We aim to bring ecological complexity to the planning tools used to inform decision making.
We are also interested in the impacts of climate change to marine ecosystems.
Our research applies both mathematical models and statistical analysis.
We specialise in integrating ecologically complex models with tools for informing decision makers. We also work with large databases of the marine environment.
The global biodiversity crisis requires new science and approaches for sustainable management of marine ecosystems. We have studied how fishing alters food-webs, sometimes even improving the productivity of fisheries.
We also study how decision makers can meet compromises between achieving productive fisheries and conserving functioning ecosystems. My recent work has focussed on the use of marine reserves in the conservation of ecosystems and the trade-offs reserves create with fisheries.
We are interested in how climate change has affected ocean ecosystems globally. We published a comprehensive meta-analysis of ocean climate change studies that was subsequently used by the Intergovernmental Panel on Climate Change in their latest assessment report. We reviewed studies that had at least 2 decades of observations of marine life and found widespread impacts of climate change to marine life have already occurred.
