Geomicrobiology and Biogeochemistry
Our group use a range of complementary approaches across spatial and temporal scales to investigate research questions.
We are a home to a diverse set of scientists who use a range of complimentary approaches across a range of spatial and temporal scales to investigate research questions in two focal areas.
Our Geomicrobiology research involves analyses of microbial communities and how they cope with their environment including biosphere-geosphere interactions.
Our Biogeochemistry research investigates the processes (biological, geological, chemical, and physical) driving the cycling of elements in the environment (including the hydrosphere, cryosphere, atmosphere and biosphere).

Dedicated geomicrobiology laboratory
The laboratory includes facilities for work with strict anaerobes and molecular biological equipment for DNA-based characterization of microorganisms and microbial communities (including PCR, qPCR).
For biogeochemical studies the lab also includes a radioisotope facility and analytical equipment (cation and anion chromatography gas chromatography).
We have a high pressure incubation vessels and pressure-retaining sediment processing equipment.
