His recent work involves simulation of the global carbon cycle using the inverse approach, characterizing fossil fuel CO2 in North America (the “Vulcan” and “Hestia” projects), the linkages between terrestrial carbon exchange and climate variability, and deforestation and carbon/climate feedbacks. He is also a member of NOAA’s Global Carbon Cycle Science Steering Committee, the international Global Carbon Project Science Steering Committee, and NASA’s Mid-continent intensive task force. He is an Associate Editor of the journal Carbon Management and a recipient of Sigma Xi’s 2010 Young Investigator Award and NSF’s 2009 CAREER award.
