I am a Research Scientist at the Pacific Biological Station (part of Fisheries and Oceans Canada) in Nanaimo, on Vancouver Island, British Columbia. I also hold an Adjunct Assistant Professor position with the Department of Biology at the University of Victoria, British Columbia. I am an ecological modeller.

Stock assessment work involves assessments for several rockfish species (Pacific Ocean Perch, Yellowmouth Rockfish, Redbanded Rockfish) along the coast of British Columbia, and for Pacific Hake in U.S. and Canadian woaters. These mainly use age- and sex-structured population models, fitted to data in a Bayesian context.

My career research interests are wide, from the smallest marine plants to the largest seabirds. The latter relates to our Nature paper that was also the focus of an article in Science. This has led to further research concerning movement patterns of a variety of foragers, including microzooplankton, grey seals and even fisherman. Current research includes working on methods for fitting size spectra models to data. Eight of my first-author papers have each been cited at least 60 times (see Google Scholar Profile).

My background is in mathematics, and my first foray into ecology was as an undergraduate NERC summer student with Dr. Simon Wood, investigating properties of the Ricker model with noise. In a pleasing turn of events, I now work where Dr. Bill Ricker did much of his work. I have done cruises on the Research Vessel W.E. Ricker, my office looks out onto a road called "Ricker's curve", and I (apparently) have a bookcase that once belonged to Dr. Ricker.

I moved to Nanaimo from the British Antarctic Survey in Cambridge, UK, where I held the somewhat uniquely-named position of Biosphere Complexity Analyst. I was previously a Research Associate in the Department of Biology at Dalhousie University in Nova Scotia on the east coast of Canada, where I worked with Dr. Ransom Myers on the impacts of industrial fishing and co-taught a course entitled 'An Introduction to Biological Modelling'. I also worked with Dr. Trevor Platt and Dr. Shubha Sathyendranath for five years at the nearby Bedford Institute of Oceanography (also part of Fisheries and Oceans Canada), on modelling of the plankton ecosystem. Before that I was in Dr. Hal Caswell's lab at the Woods Hole Oceanographic Institution, USA, also working on plankton modelling. I obtained my Ph.D. in Applied Mathematics, supervised by Prof. John Brindley at the University of Leeds, UK.
