Curtis Suttle

Curtis Suttle is a Professor in the Department of Botany at the University of British Columbia's Faculty of Science. He also holds affiliations with Earth and Ocean Sciences, Microbiology and Immunology, and the Institute for Oceans and Fisheries. His research focuses on marine virology and the ecological roles of viruses in aquatic ecosystems, particularly their impact on phytoplankton and microbial communities.

Dr. Suttle received his B.Sc. and Ph.D. from UBC, was a Coastal Marine Scholar at SUNY StonyBrook (1987-88), and served as Assistant/Associate Professor at the University of Texas at Austin (1988-96) before returning to UBC.

His research program investigates the biology and ecology of viruses that infect microalgae and cyanobacteria. Key areas include discerning viral effects on primary productivity, isolating novel marine viruses, developing molecular identification methods, and studying viral distribution patterns. His work has revealed that viruses can occur in seawater at concentrations exceeding 10⁵ ml^-1, with cyanophage concentrations reaching 10⁶ infectious units ml^-1 in coastal waters. Dr. Suttle's team has developed PCR primers specific for viral DNA polymerase genes, showing these viruses belong to a single family related to herpes viruses.

Recent publications show a strong focus on marine viral ecology, with particular attention to oyster microbiomes, viral taxonomy, and the role of viruses in marine ecosystems. His research spans from coastal environments to the deepest ocean trenches, examining viral diversity across environmental gradients and investigating viral impacts on carbon cycling and marine food webs.

Dr. Suttle leads an active research group with several post-doctoral associates, research scientists, and graduate students. His team conducts field work at multiple locations including the Naica Mine in Mexico, Pavilion Lake in British Columbia, Saanich Inlet, and the Strait of Georgia. Current projects include collaborations with the Hakai Institute, Line P Research Cruise, and CASES (Canadian Arctic Shelf Exchange Study).

His laboratory has made significant contributions to understanding viral roles in marine ecosystems, particularly through expeditions to extreme environments like the Naica crystal caves and deep ocean trenches. Ongoing research explores viral impacts on microbial community structure, carbon cycling, and ecosystem function across diverse marine habitats.
