The terrestrial carbon, water and energy balances are key components of the Earth system which are highly linked. Therefore, I have a long-term interest in understanding their coupling due to various processes and at different scales. My geographical focus is on northern hemisphere ecosystems. One topic of the research group is to mechanistically understand atmosphere-land exchanges of CO2, CH4 and water, and in particular due to permafrost carbon dynamics. Another topic concerns northern high latitude vegetation carbon stocks pattern in relation to climate. In addition, a new focus is on lateral export of carbon to freshwater systems and the fate of carbon within these systems. One leading question is what will be implications of climate change on permafrost states and subsequent effects on the vertical and lateral carbon processes. An interesting sub-question is, what are effects of variability of meteorological variables and extreme events on these vertical and lateral ecosystem processes?
