My primary research interest is soil chemistry, in particular the biogeochemistry of mercury. A strong focus is the linkage between chemical speciation and methylation/demethylation reactions in sediments. At present, I am also involved in several projects dealing with mercury biogeochemistry in the boreal forest landscape, e.g. in wetlands and on forest clear-cuts.
