I work at the interface between terrestrial and aquatic carbon cycling, with a focus on organic-rich environments such as peatlands and wetlands. Currently I am using a suite of measurements to identify potential positive climate feedbacks in the Arctic. This includes quantifying fluxes using eddy-covariance, intensive field sampling campaigns, and radiocarbon dating of dissolved methane, carbon dioxide and organic carbon fluxes in rivers, streams, lakes and ponds of the far east Siberian Arctic. I also have several ongoing collaborations looking at the wider significance of the mobilization of carbon into inland waters across a range of environments using geochemical, micro-meteorological and microbial techniques in the field and in lab-based experiments. I am based in both the Ecology and Earth Sciences departments at the VU Amsterdam. My previous work includes groundwater and surface water hydrology and geochemistry, as well as geomorphology.
