Geology, Queens's University, Kingston 1986 B.Sc. Honours Geography, Carleton University, Ottawa Relevant Experience: Dr. Wolfe obtained a PhD in geography in 1993 from the University of Guelph, specializing in sparse vegetation as a surface control on wind erosion. Dr. Wolfe has been with the Geological Survey of Canada as a research scientist since 1996, and is presently also an adjunct professor at Carleton University and the University of Victoria. Dr. Wolfe’s recent research activities include the geomorphic and environmental response of sand hills on the Canadian prairies to past, present and future climatic conditions and the impacts on and effects of land use management strategies. He has examined the formation and Holocene evolution of sand dunes in the northern Great Plains and Yukon, and coastal dunes and beaches in the Queen Charlotte Islands, British Columbia. He has co-supervised students on the topics of morphology, stratigraphy and sediment transport of active sand dunes in continental and coastal settings. Dr. Wolfe is currently Vice-President of the Canadian Geomorphological Research Group, an Associate Editor of the scientific journal Géographie Physique et Quaternaire, and a member of the Quaternary Geology and Geomorphology Subdivision of Geological Society of America. In 2002, he received the CGRG J. Ross MacKay Award in recognition of significant achievement by a young geomorphologist in Canada for his work on “Impact of increased aridity on sand dune activity in the Canadian Prairies”. Dr. Wolfe has led the project "Paleo-environmental Records of Climate Change", within the Climate Change program for three years. He has edited several journal issues on the topic of paleoenvironmental change on the Great Plains of US and Canada and on eolian geomorphology. He has also edited a series of GSC publications on the response of active geomorphic processes to climate change. Dr. Wolfe has provided his expertise and advice, on behalf of NRCan, in the Federal Environmental Assessment several environmental assessments pertaining to northern diamond development (Ekati Diamond Mine Project; Diavik Diamonds Project); Jericho Diamond Mine Project), and southern wind farms.
