Geomicrobiology and Biogeochemistry
We study interactions between life, geology and environmental chemistry to unravel biogeochemical processes important for Earth’s habitability through Earth history.
The Geomicrobiology and biogeochemistry group unites cross-disciplinary scientists in microbiology, biology and geochemistry.
We investigate the linkages between geomicrobiology and biogeochemistry to explain key biogeochemical processes that sustain ecosystems at local to global scale.
Research
Geomicrobiology
The Geomicrobiology unit studies diverse ecosystems, ranging from marine to terrestrial, from the surface to the deep continental and marine biosphere, spanning the modern to the ancient earth where life evolved.
We use the evidence to unravel how microbial life interacts with geological processes, minerals, metals and with each other to produce and maintain the major biogeochemical cycles that are key to earth’s habitability.
Biogeochemistry
We combine geomicrobiological observations with geochemistry to unlock Earth’s biogeochemical history. This multidisciplinary work which connects the geomicrobiology and geochemistry units, allows the application of high resolution geochemical methods for investigating how geomicrobiology and geochemistry function together in the environment.
Researchers are interested in identifying and using biogeochemical signals as proxies for unravelling how life interacts with geochemistry to create and sustain the living biosphere.
