Steve Whitlock joined the staff at Columbia Basin Research after earning a Ph.D. in Fisheries Science at Oregon State University in 2019. He holds a B.S. in Biology from Northland College, as well as a M.S. in Fisheries Science and a Graduate Academic Certificate in Statistics from the University of Idaho. Dr. Whitlock has worked with numerous Federal, State, and Tribal Agencies and his past research experience includes studying effects of water level fluctuations on spawning kokanee in Idaho, and Pacific lamprey spawning ecology and dam passage in the Willamette Basin. Though most of his research background is related to studying freshwater fish, he has also designed tailored models for describing populations of sea birds, pinnipeds, and humpback whales.

Research Interests

Broad interests include developing novel analysis methods and software tools to assist researchers and decision makers with challenging aquatic resource management and conservation issues. Dr. Whitlock's current work focuses on using retrospective analyses to evaluate and recommend improvements to multiple facets of juvenile salmon acoustic telemetry studies in the Columbia River and San Joaquin Delta.

Areas of Expertise

  • Hierarchical modeling
  • Hydroproject passage and survival studies
  • Pacific lamprey ecology
  • Structured decision making and the development of decision-support tools
