James Randerson studies the global carbon cycle using remote sensing and in-situ measurements and different types of models. Current research themes in his laboratory include climate-carbon cycle feedbacks, land use change, and the effects of fire on ecosystem function and atmospheric composition. He has conducted field work in Alaska and Siberia to assess the long-term impacts of fire on surface energy exchange and fluxes of carbon dioxide. Randerson was born in Fairfax, Virginia and grew up in San Diego, California, where he attended Point Loma High School. He received a BS in chemistry (1992) and a PhD in biological sciences (1998) from Stanford University. He conducted postdoctoral work at UC Berkeley and University of Alaska before joining the faculty at Caltech. In 2003, Randerson moved to UC Irvine where he now holds the position of Ralph J. and Carol M. Cicerone Professor of Earth System Science. Randerson was the recipient of the James B. Macelwane Medal in 2005 and the Piers J. Sellers Global Environmental Change Mid-Career Award in 2017 from the American Geophysical Union. Randerson served as co-chair of the biogeochemistry working group of the Community Earth System Model from 2003-2017 and is currently a member of the Biological and Environmental Research Federal Advisory Committee for the U.S. Dept. of Energy Office of Science. He is a Fellow of the American Geophysical Union and a member of the U.S. National Academy of Sciences.
