climate change risks and impacts
paleo glacial-interglacial transactions
Areas of expertise
My present research field can be described broadly as the dynamics of terrestrial ecosystems, including carbon cycling, and their interactions with the climate system. In particular, I am interested in how the terrestrial biosphere and terrestrial carbon fluxes respond to changes in climate on various time scales such as interannual variability, future global warming but also paleo glacial-interglacial transitions. An important aspect of this research is to quantify the anthropogenic perturbation on the carbon cycle and with it the detection of measures to mitigate climate change. To this end, I am using observational data and data assimilation techniques to optimise models of the Earth System.
My research also focuses on the large question of what constitutes 'dangerous climate change' and to assess the risks of climate change on ecosystems.
