Ian Walker was one of the founding directors of the British Columbia Lake Stewardship Society. He is a former member of NSERC’s Environmental Earth Sciences Committee and serves on the Advisory Board for the Journal of Paleolimnology.
Ian has held Guest Professorships at the Geobotanical Institute, University of Bern, Switzerland, and the Department of Physical Geography & Quaternary Geology at Stockholm University.
His research interests pertain especially to limnology, palaeoecology, freshwater mussels, and the biology of one family of freshwater insects, the Chironomidae. He is developing the Chironomidae as quantitative indicators of past environmental change. These environmental changes include lake eutrophication, climatic change, and past changes in lake water salinity.
