Roger coordinates the museum's Laboratory of Molecular Biodiversity where staff, students and volunteers use molecular techniques to contribute to the research projects at the Canadian Museum of Nature. The lab is a constant hive of activity. On any given day, members of the lab team will be extracting, replicating and sequencing DNA to learn how living things are related to each other. They also use the DNA to identify organisms, which range from plants, birds and mammals to crustaceans and other invertebrates such as clams and snails.

Roger also works in the field with the museum's botany team to document the plant life of the Canadian Arctic, which may be affected by the changing climate. Roger previously studied seabirds in Nunavut for the Canadian Wildlife Service as well as forest birds in Southeast Alaska and Haida Gwaii, British Columbia, for his graduate research.
