Research Scientist

My role includes evaluating management strategies for Pacific salmon, among other species.

Fisheries and Oceans Canada

Current research and/or projects

The goal of my research program is to develop tools to facilitate communication and decision-making at the interface between fisheries science and management in three broad areas. I am interested in identifying and evaluating biological benchmarks of population status of Pacific salmon and reference points for management. In addition, my program focuses on the integration of oceanographic information into models of salmon population dynamics to improve science advice to management. I am further interested in how the spatial dimension of ecological processes affects the distribution of fish species, and the implications for fisheries management. In my role coordinating assessments under Canada's Wild Salmon Policy, I am leading the development and evaluation of new methods for Pacific salmon to inform management plans.
