Research interests

Since 1989, I have conducted research on many aspects of seabird biology and marine ecology in Alaska, Canada's eastern Arctic, Newfoundland and Labrador, and British Columbia. Research topics that have been of particular interest include: (1) the evolutionary ecology of the Alcidae; (2) parental investment decisions, especially related to egg production and chick provisioning; (3) causes and consequences of variation in the size and composition of eggs, both within and among species; (4) factors affecting offspring growth and development, and their consequences for condition at time of nest departure and recruitment; and (5) ecological and demographic responses of seabird populations to environmental variability. The publications listed below give an idea of the range of topics addressed in my research.

Since 2001, I have directed the Centre for Wildlife Ecology's seabird research and monitoring program at Triangle Island, British Columbia. This program aims to integrate pure and applied science to provide a more comprehensive understanding of seabird biology. Ultimately, we hope to provide the information necessary to enable the Canadian Wildlife Service to enact effective conservation strategies for marine wildlife. Follow the link to learn more about Triangle Island and the CWE's seabird research program, including former and current graduate student projects.
