Welcome to my website!
As a biostatistician 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 continue to develop new skills, including GIS, machine learning, and neural networks. I also publish on matrix population models, demonstrating modern ways of shrinking any population matrix to one of smaller dimension (model aggregation), and measuring transient dynamics.
