I am a senior research scientist at the Norwegian University in Life Sciences, Faculty of Environmental Sciences and Natural Resource Management. Since 1999, I was appointed as Post Doc, research scientist and project leader in several projects related to metal speciation in soil, sediments and fresh water and the impact of metal speciation on the soil biology. My general field of expertize is within soil science with a special focus on the biogeochemistry of trace  elements. Hence the metal speciation in soil solution and it´s impact on both soil microbial biology and plants have had special focus. I have also developed good expertize in the assessment of risk of metal contaminated soils, sediments and water. During most of my career I have used several techniques to investigate metal speciation in environmental samples using i.e. anodic stripping voltammetry (visiting scientist at Cornell University) WHAM/Model VI (Windermere Humic Aqueous Model, visiting scientist at the Centre of Ecology and Hydrology, UK) and DGT (diffusive gradients in thin films) technique. I have and am currently supervising a number of PhD and MSc students and collaborating with partners around the world. In 2014 I was evaluated as professor competent (1183). At NMBU, however, my position formally remains as a research scientist.

Along the environmental focused research line, I have been, and still am, involved in more directly agricultural related projects in Norway and elsewhere (Asia, Africa). Common for these projects is that I have and am involved in parts related to determination of trace element (e.g. Cd, Zn, As) and major element (P) speciation in soil and their biogeochemistry in soil plant systems using WHAM and/or DGT/DIFS. Despite its´ not my expertise, I am increasingly taking part as partner for investigating climate change related impacts on management of agricultural systems. This is focused on soil erosion, soil organic carbon sequestration and soil degradation in East Africa. Most of these projects involve supervision of MSc and PhD students.
