    As an interdisciplinary ecogeochemist, my research interest lies at the interface of geochemistry, ecology and ecotoxicology. Specifically, my aim is to assess the role of biota in geochemical cycles with a particular focus on mining derived contaminants in frontier ecosystems such as Alpine and Arctic environments. Using state of the art geochemical tools, i.e. total-chemistry from ICP-MS and DMA, as well as ecological- and isotopic-tracers (δ13C & δ15N, 86-87Sr, 206-208Pb, 199-204Hg), my work also aims to quantify aboveground/belowground linkages, trophic interactions and the transfer efficiency of essential and non-essential elements in Alpine and Arctic ecosystems and the link of such elements to the health of wildlife.
