From 1960-1965, he worked as a Canadian Wildlife Service biologist, specializing in polar bear and muskox research. In 1965, he was appointed Curator of Quaternary Zoology with the National Museums of Canada and was Chief of the Paleobiology Division (1982–1991). He carried out detailed studies of the ice age animals of the Yukon, concentrating his work on the unglaciated country near Dawson and Old Crow; and on Pliocene vertebrates and environments of Ellesmere Island where he spent 10 field seasons between 1992 and 2008 leading a team collecting fossils from a unique 4 million-year-old vertebrate site (the Beaver Pond site) near the head of Strathcona Fiord. His interests include: the ice age vertebrates of Canada, Alaska and Greenland; the evolution and distribution of arctic and alpine mammals; and climatic change in Canada during the ice age. He has written or contributed over 300 scientific papers, publications and reports." |
