Dear Colleagues, The Department of Geosciences, at the Swedish Museum of Natural History, Stockholm, Sweden, offers a three-year interdisciplinary postdoctoral position combining field petrology, field and laboratory experiments in mineral-water interaction, and hydrochemical modelling. The project is aiming to develop new knowledge of the metamorphic bedrock as a source of arsenic (As) contamination. The project seeks to identify and quantify the distribution of risk lithologies, quantify the processes using leaching tests (field and laboratory experiments), and perform geochemical modelling with special emphasis on how the petrology of rocks affects the As leaching and in what form As spread to the environment. Field work is mainly focused on the Precambrian amphibolite to granulite facies metamorphic domains in central Fennoscandia. The project is carried out in collaboration with the Department of Geological Sciences at the Stockholm University and the Department of Sustainable Development, Environmental Science and Engineering at KTH Royal Institute of Technology, both departments located in Stockholm, and the Department of Mineralogy, Petrography and Geochemistry at the AGH University of Science and Technology in Krakow, Poland. Part of the laboratory work will be located at the AGH University. The postdoc will be appointed for a three-year position at the Museum of Natural History in Stockholm. Principal work tasks will include participating in the fieldwork, design and execution of leaching experiments, investigation and characterisation of rocks and minerals using optical, electron and Raman microscopy, and geochemical modelling. The successful candidate will also have the possibility to develop its own line of research. The project is fully funded by the Swedish Governmental Research Council for sustainable development, FORMAS. A start date in January-May 2026 is anticipated.
