Ian Taylor is a native of the Pacific Northwest. He received his B.A. in Mathematics from Carleton College in 1997. He then taught mathematics in rural Zimbabwe for the U.S. Peace Corps before returning to Seattle to attend graduate school at the University of Washington. Ian received a Ph.D. in the Quantitative Ecology and Resource Management in 2008. His work under Dr. Vincent Gallucci focused on the population dynamics of Spiny Dogfish in the N.E. Pacific, including estimating movement and abundance, patterns of tagging data, and alternative measures of stock status. Ian joined the NWFSC as a post-doc in 2008 working with Drs. Richard Methot and André Punt. In 2010, Ian joined the FRAM stock assessment team.

Current Research

Ian has contributed to stock assessments for Spiny Dogfish, Yelloweye Rockfish, Darkblotched Rockfish, China Rockfish, Shortspine Thornyhead and Longspine Thornyhead. He is one of two U.S. representatives to the Joint Technical Committee which conducts the stock assessment for Pacific Hake under an international treaty with Canada. His research focuses on testing and improving stock assessment methods. Ian is also lead developer of R4SS, a software package in the language R used for working with the Stock Synthesis stock assessment platform. In 2015, he was awarded the NOAA Technology Transfer Award for this effort. Through this software package, which is available at, Ian has worked to improve the efficiency of the stock assessment process and the ability for assessment authors explore and communicate the results of their models. Ian also continues to work with Dr. Methot on testing and expanding the Stock Synthesis assessment modeling platform.
