Jim uses statistical methods and mathematical modeling to describe ecological processes and inform management decisions. Jim has been at the Northwest Fisheries Science Center since 2005. He previously worked as a statistician for cancer research studies. Jim holds a B.S. in Wildlife Science (1999) and an M.S. in Statistics (2001), both from Oregon State University. He is currently completing a Ph.D. in Quantitative Ecology and Resource Management at the University of Washington.
Jim’s work focuses mainly on survival estimation of juvenile and adult salmon using capture-recapture methods, and on developing models to describe the passage experience of salmonids through the hydropower system on the Snake and Columbia Rivers. These passage models help inform the Comprehensive Passage Model (COMPASS), which is used for in-season predictions and for investigating management scenarios. His research interests involve the development of mathematical and statistical models for ecological and evolutionary processes.
