Research area(s):

  • Fisheries oceanography
  • Fisheries science and management
  • Pacific salmon

Area of Expertise:

Dr. Walters’ areas of research include the development of rapid techniques for teaching systems analysis and mathematical modeling to biologists and resource managers. His primary foci are fish population dynamics, fisheries assessment and sustainable management. He has undertaken extensive fisheries advisory work for public agencies and industrial groups.

A member of several of NSERC’s grant committees since 1970, he has done extensive fisheries advisory work for public agencies and industrial groups. He has also conducted over two dozen three to ten day workshops in the past decade, for the International Canadian Fisheries Service, US Fish and Wildlife Service and the International Institute for Applied Systems Analysis. In 1992, he gave the keynote address to the American Fisheries Society, entitled: Where have all the Coho Gone?

Alongside Villy Christensen and Murchdoch McAllister, Dr. Walters works in the UBC Quantitative Modelling Group. The Quantitative Modelling Group develops mathematical models to help fisheries biologists and resource managers adapt in the face of the extreme uncertainty that characterizes many marine ecosystems. The group focus on Bayesian statistical methods and dynamic population models is aimed at assisting fisheries risk assessment, estimation, decision analysis and management strategy evaluation. Partnerships with colleagues within and outside UBC have generated a continuum of projects ranging from factors affecting species composition in small B.C. lakes to ecosystem management in the Gulf of Mexico.
