I am a Postdoctoral Fellow at Simon Fraser University with Dr. John Reynolds, Dr. Brendan Connors, and Dr. Martin Krkosek. My postdoctoral research examines the population dynamics and conservation status of salmon populations on the Central Coast of British Columbia.
Pacific salmon have a key ecological, economic and cultural role throughout their range. However, the factors driving spatial and temporal variation in the productivity of salmon populations are poorly understood. Understanding these patterns in productivity is important for coastal First Nations, who in recent years have taken on an increased role of the management of salmon in their traditional territories. My research is being done in collaboration with the Central Coast Indigenous Resource Alliance, Simon Fraser University, the University of Toronto, the , and Fisheries and Oceans Canada. I am synthesizing salmon population data from the Central Coast of BC to quantify patterns, identify information gaps, and confront key hypotheses to inform conservation and management. This research is an extension of some of my previous research in that I am interested in understanding the drivers of variation in salmon population productivity at multiple scales.
