Lars O. Hedin is a Professor in the Department of Ecology and Evolutionary Biology at Princeton University. His research focuses on ecosystem analysis, emphasizing global nutrient cycling patterns, greenhouse gas dynamics, and evolutionary influences on biogeochemical systems. He leads interdisciplinary studies spanning local microbial processes to global ecosystem controls.

- Ph.D., Biogeochemistry and Ecosystem Studies, Yale University (1989)
- M.S., Biogeochemistry and Ecosystem Studies, Yale University (1986)
- B.S., Ecology and Evolutionary Biology, Cornell University (1983)
Research Interests:
- Nutrient cycles in temperate and tropical forests
- Macroscopic ecosystem properties emerging from Darwinian selection
- Biophysical controls on methane exchange in soils
- Global impacts of human activities on biogeochemical systems
- Development of isotope techniques for microbial methane analysis
Professional Experience:
- Chair, Princeton Department of Ecology and Evolutionary Biology (2014–present)
- Director, Princeton Environmental Studies Program (2010–2014)
- Acting Director, Princeton Environmental Institute (2011–2012)
- Professor at Princeton University (2001–present)
- Associate/Assistant Professor at Cornell and Michigan State Universities
Teaching:
- Princeton: EEB417 (Ecosystems and Global Change), ENV201 (Environmental Systems), graduate seminars on nutrient cycles
- Cornell: Courses in ecosystem biology, biogeochemistry, and environmental studies
Labs and Teams:
- Leader of the Hedin Lab, conducting field studies in remote forests (Chile, Argentina, Hawaii, Amazon, Africa)
- Collaborative development of methane isotope pool-dilution techniques
