I am interested in the landscape carbon (C) balance and particular the influence of streams, lakes and coastal areas and their function as processors of C and as conduits for transferring C across the terrestrial/aquatic/atmosphere interfaces. Much of my research focus on 1) the terrestrial/aquatic hydrochemical connectivity and how it is affected by human disturbances. 2) aquatic/atmospheric interactions with focus on controls of the exchange of C between water and air.
I am course leader for Geology and Hydrology (Mv0226), 7.5 hp which is given within the bachelor programs in Biology and Environmental science, and Crop production. I have also teaching within the courses Natural resources for energy systems in a biogeochemical perspective (BI1360) and Environmental Assessment (Mx0152).
