Current research and/or projects

I am interested in the development of practical, precautionary, ecosystem approaches to fisheries management and in their application, in particular to the eastern Scotian Shelf shrimp (Pandalus borealis) stock. More recently I have worked on the phenology of P. borealis and phytoplankton using satellite remote-sensing to elucidate the mechanisms behind longstanding but unexplained correlations between shrimp abundance and environmental parameters. The results have direct applications in shrimp assessments incorporating environmental and ecosystem considerations. My contrasting experiences in the conservative discipline of stock assessment and the more progressive but often more theoretically-oriented field of fisheries science have also led to an interest in the philosophy and psychology of science (in addition to major headaches).
