I am an expert in the foraging ecology and breeding biology of marine birds, in particular alcids and gadfly petrels. My research has taken me to remote islands off the British Columbia coast, the Galápagos Islands, and to the Robinson Crusoe Islands in Chile.

Since 1987, I have studied birds at sea and on their breeding colonies. Using a combination of field observations, long-term banding, bird-borne data loggers and remote sensing data, my research has answered questions related to life history tradeoffs, response to oceanographic conditions, identification of key foraging habitats, and the spatial-temporal overlap with commercial fisheries.
