Roger Bull works at the Canadian Museum of Nature where is the Head of Operations of the National Biodiversity Cryobank of Canada, a frozen library of tissue samples for genetic research. He also heads the operations of the museum’s Laboratory of Molecular Biodiversity where students and researchers study mysteries of the natural world by unlocking information in DNA molecules. As a member of the museum’s field botany team, Roger has travelled to the Canadian Arctic to participate in field research that documents Arctic plant life. This research collects crucial baseline information for understanding the effects of the changing climate on northern plant communities. Roger is obsessed with cross-country skiing. If there is snow on the ground, you’ll probably find him training for the Canadian Ski Marathon, a 160 km event that takes place every February in western Québec.
