    Biography

    Education:

    • Ph.D. in Mechanical Engineering, Concordia University (2009)
    • M. Eng. in Mechanical Engineering, Concordia University (2003)
    • B.Eng. in Mechanical Engineering, Concordia University (1999)

    Prior to joining the University of Saskatchewan in November 2014, Dr. Cree worked on a three year contract at Queen’s University as an Assistant Professor in the Department of Civil Engineering. As the founding Director, he was instrumental in the implementation of Aboriginal Access to Engineering at Queen’s University, an initiative design to encourage engineering as a career option for Aboriginal students. He completed a National Science and Engineering Research Council of Canada (NSERC) Post-Doctoral Fellowship at Queen’s and was also a recipient of the 2011 National Aboriginal Achievement Award in the category of Technology and Trades. More recently (2014) he was awarded The Dreamcatcher Award for Education from the Dreamcatcher Charitable Foundation. Dr. Cree has been a junior engineer for Bombardier Aerospace, Pratt and Whitney Canada and the National Research Council’s Flight Research Laboratory. He is also a licensed professional engineer in both provinces of Saskatchewan and Ontario. Each year he participates as a judge in the Quebec Aboriginal Science and Engineering Association annual science fair for Aboriginal high school students.

    Dr. Cree’s research interest is in the area of materials science, specifically understanding the mechanical behavior of engineering materials. His research work focuses on novel, sustainable materials such as natural fibre/bio-resin composites. His current work is used to optimize chemical treatments of fibres and fire retardants in polymer resins to improve fibre/matrix adhesion and elevated temperature performance in tension and lap-splice configurations, respectively. Past work includes polypropylene fibre additions to concrete in order to prevent explosive spalling as well as elevated temperature mechanical properties of concrete containing recycled aggregates from demolition waste of construction and building materials. He has also investigated the use of eggshell powder as a partial replacement of natural quarried limestone for a variety of engineering applications.
