A biostatistician with 30 years of experience



Welcome to my website!

As a biostatistician based in Seattle, I've spent the past three decades developing passage, life-cycle, and population viability models for pacific salmon. Along the way, I also wrote articles on 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-baseds tagging. I continue to develop new skills, including GIS, machine learning, and neural networks.
