William Colgan has been an Assistant Professor in the Department of Earth and Space Science and Engineering since 2015, and is currently European Space Agency (ESA) Living Planet Fellow in developing satellite data products to assess ice loss from the Greenland Ice Sheet. Dr. Colgan completed his Ph.D. in Geography at the University of Colorado at Boulder in 2011, and joined the department after three years as a post-doctoral fellow with the Geological Survey of Denmark and Greenland in Copenhagen. Dr. Colgan has participated in ten research expeditions to the Canadian Arctic, Greenland and Antarctica to take in situ measurements of glacier-climate interactions and collect validation data for satellite observations and computer simulations. Dr. Colgan also has a strong research interest in the emerging field of applied glaciology challenges associated with mining projects that interact with glaciers. He is currently a member of the executive council for the International Glaciology Society (IGS), as well as a member of the advisory board for the Canadian Cryospheric Information Network (CCIN). Dr. Colgan’s primary teaching interest is Climate and Climate Change (ESSE4160).

Research Interests

  • In situ observations of glacier-climate interactions
