I am a geochemist with a particular interest in biogeochemical cycling of metals/macro-nutrients and their responses/feedbacks to human activities and environmental changes.

Teaching

I teach courses in the Environmental Science and Sustainability Programme. Another important part of my teaching is to supervise Bachelor, Master, and PhD students.

Research

My research mainly focuses on biogeochemical processes of Fe and Mn, as well as their (i) impacts on the mobility, transport and environmental fate of potentially toxic or biologically critical trace elements (e.g., U, Ni, As, and REEs); and (ii) links to organic carbon storage/turnover and nutrient (e.g., Si, S, and N) cycling in (sub-)surface environments. To obtain a fundamental understanding of these processes and link them to the processes and phenomena at landscape scales, we combine conventional (bio)geochemical analyses with a wide range of state-of-the-art imaging, spectroscopy, and mass-spectrometry techniques (e.g., XAS, STXM, FTIR, GC-MS, and FT-ICRMS), isotope characterizations, and modern theoretical simulations (e.g., DFT) via collaborations with both national and international groups.

My research projects are funded by The Swedish Research Council Formas, Geological Survey of Sweden, and EU Botnia Atlantica.
