Marie has also been an active member of Alberta’s environmental community for over two decades as a graduate student, conservation scientist in the government and non-profit sectors, and board member of Nature Calgary and Alberta’s Prairie Conservation Forum. Marie lives in Calgary and when she is not working loves to explore southern Alberta’s diverse natural environments by foot, ski or paddle with her family and friends.
