Aquatic and soil geochemistry

The main purpose of our research is to contribute with fundamental knowledge about the complex processes that take place at naturally occurring interfaces in soil and water, thereby contributing to the basic understanding of our environment.

The composition of the Earth's surface and the properties of ecosystems are intimately linked to the biogeochemical cycles of the elements. These cycles are regulated by interactions at interfaces between microorganisms, mineral particles and aqueous solutions, and are often driven by electron transfer reactions. Such interactions and reactions determine, for example, the transport and bioavailability of nutrients and pollutants in the environment, and whether soil organic material breaks down into carbon dioxide or is stored in soils for longer periods of time.

 In our group, we combine a range of competencies in chemistry, biology and physics, and use a broad experimental approach that includes spectroscopy, scattering and hyperspectral imaging techniques, some of which are synchrotron-based, as well as wet chemical and theoretical methods.
