Maija is postdoctoral research fellow in geomicrobiology. She is working on a project to examine the biogeochemistry of Mg-carbonates in the sediment of hypersaline lakes. She is interested in deep subsurface microorganisms and in sulphur, iron and methane biogeochemical cycling in sedimentary and subsurface environments. Her PhD (The University of Queensland) focused on biogenic methane production and consumption in two Australian underground coal mines. In 2016, she was a shipboard microbiologist on IODP Expedition 370 (T-limit of Deep Biosphere off Muroto) and is working to culture thermophilic iron reducers and methanogens from the deep subseafloor.
