Roger is the head of operations at the National Biodiversity Cryobank of Canada (NBCC), a genomic resource biorepository of tissue and DNA samples stored in freezers cooled by liquid nitrogen to less than -160°C. At this low temperature, the information encoded by DNA molecules is preserved in perpetuity. This collection is a frozen library of genetic information about the natural world and is available to biodiversity researchers at the museum, in Canada and around the world.

Roger also heads the operations of the museum's Laboratory of Molecular Biodiversity where staff, students and volunteers use molecular techniques to contribute to genomic research projects at the Canadian Museum of Nature. The lab is a hive of activity where members of the lab team extract, amplify and sequence DNA to identify new species and to learn how living things are related to one another.

Roger has also worked in the field with the museum's botany team to document plant life in the Canadian Arctic. He previously studied seabirds in Nunavut for the Canadian Wildlife Service and forest birds in Southeast Alaska and Haida Gwaii, British Columbia, for his graduate research.
