Dr. Peter Thornton studies the interactions of land ecosystems with other components of the Earth's climate system including biogeochemical and physical land-atmosphere feedbacks, and interactions with human systems.
For the third consecutive year, Dr. Peter Thornton has been recognized for exceptional research.
