Roger Bull is a scientist at the Canadian Museum of Nature in Ottawa. He runs the museum’s Laboratory of Molecular Biodiversity where researchers study mysteries of the natural world by unlocking information in DNA molecules. Roger also participates in field research to document the plant life of the Canadian Arctic. This is crucial baseline research for understanding the effects of a changing climate on northern plant communities. Roger spent two weeks setting up the C3 science labs before the expedition began. He’s excited to be joining the Canada C3 science team for the final leg of the journey!
