As a statistician/population modeler based in Seattle, I spent the past three decades developing passage, life-cycle, and population viability models for pacific salmon. I have published articles on salmon, Eulachon, and American shad. I create tools used to design research, monitoring, and evaluation programs, including the estimation of the proportion of hatchery-origin fish on the spawning grounds using parentage-based tagging. I also published on matrix population models, demonstrating modern ways of shrinking any population matrix to one of smaller dimension (model aggregation), and measuring transient dynamics. I introduced to matrix population modeling the concept of balancing, which transforms a population projection matrix to account for differing values of stages. I continue to develop new skills, including GIS, machine learning, and neural networks.
