Brett Walker

Brett Walker is an Associate Professor in the Department of Earth and Environmental Sciences at the University of Ottawa, holding a Canada Research Chair (Tier II) in Accelerator Mass Spectrometry and Marine Biogeochemistry. He specializes in studying marine carbon and nitrogen cycles using isotopic and radiocarbon dating techniques.

Education: PhD in Ocean Sciences (2010), University of California, Santa Cruz (USA). Postdoctoral research at UC Irvine’s Keck Lab, followed by roles as Project Scientist and Associate Researcher there before joining the University of Ottawa in 201X.

Research focuses on microbial transformation of organic matter, ocean carbon storage, and modern to millennial-scale biogeochemical processes. His lab, the Marine Organic Geochemistry group, employs δ13C, δ15N isotopes, 14C dating, and advanced analytical chemistry.

Awards: 2018 CRC Tier II appointment highlights his contributions to marine biogeochemistry. His work bridges geochemistry and oceanography, addressing global climate-related questions.
