Peter Raymond is the Oastler Professor of Biogeochemistry at Yale School of the Environment, with an appointment in the Department of Earth and Planetary Sciences, positioning him within Yale's Geoscience faculty. He earned a B.S. from Marist College and a Ph.D. in Marine Science from the College of William and Mary in 1999. After completing postdoctoral research at the Marine Biological Laboratory and Woods Hole Oceanographic Institution from 1999 to 2002, he joined the Yale School of the Environment in 2002 on the tenure track, advancing to full professor in 2010. In addition to his professorship, he holds key administrative roles including Senior Associate Dean of Research, Director of the Yale Analytical and Stable Isotope Center, Director of Doctoral Studies, Chair of the Climate Change Learning Community, and Head of the YSE Climate Initiative. He also serves as Co-Director of the Yale Center for Natural Carbon Capture and was past Editor-in-Chief of the American Geophysical Union’s journal Global Biogeochemical Cycles. Raymond has advised 13 postdoctoral associates, 19 research master’s students, and nine doctoral students, and leads grants exceeding $10 million as principal investigator, including a $5 million U.S. Department of Energy Energy Earthshot project on carbon dioxide removal.

Raymond's research focuses on the chemistry and ecology of inland waters, including greenhouse gas exchanges between inland waters and the atmosphere, controls on terrestrial element transport to inland and coastal waters, aquatic ecosystem metabolism, and the impacts of storms and droughts on aquatic ecology. He utilizes radiocarbon measurements to assess carbon age and turnover in aquatic systems and explores natural climate solutions. His seminal publications include "Global carbon dioxide emissions from inland waters" (2013), "The global methane budget 2000–2017" (2019), "Riverine coupling of biogeochemical cycles between land, oceans, and atmosphere" (2011), and "Significant efflux of carbon dioxide from streams and rivers in the United States" (2011), amassing over 37,000 citations. Recognized as a Highly Cited Researcher from 2020 to 2023, he has received the American Geophysical Union Fellowship (2024), Fellowship of the American Association for the Advancement of Science, membership in the Connecticut Academy of Science and Engineering, Coastal and Estuarine Research Federation’s Cronin Award (2005), NSF CAREER Award (2006), and Fulbright Scholarship (2016).
