Current research and/or projects

My current work focuses on employing genetic data to support the management of several large-scale fisheries in British Columbia. I also perform research that examines trade-offs in aquatic resource management by developing quantitative tools for assessing actions under uncertainty. Some examples include the in-season management of Fraser River sockeye salmon, an ecosystem model to evaluate the survival of coho salmon in the Strait of Georgia, and a population viability analysis to estimate the responses of resident killer whales to Chinook abundance.
