Research

Human activity is directly altering the earth system via atmospheric CO2 emissions from fossil fuels and land use and land cover change. These emissions result in feedbacks to the climate and to ecosystem functioning and sustainability. We need to better understand the impact of these environmental change agents on the terrestrial carbon cycle and vegetation in order to adapt to, or mitigate, the harmful impact of climate change and human activity on our environment and society. Addressing this issue is core to my research program.
