Mineral facilitated horizontal gene transfer in the Molecular Geobiology Group
We work in the cross field between geology, mineralogy, interfacial geochemistry, geomicrobiology, biology and chemistry. The interface between biology and mineralogy are vital for many aspects of life and health and we apply in-situ molecular- to macro scale techniques to study bio-mineral associations.
Research focus
Currently we (group and collaborators) are focused on establishing fundamental information on:
- How and why minerals can preserve DNA and proteins across time and space
- How transfer of extracellular DNA adsorbed to substrates such as plastics, minerals and tissue can benefit bacterial evolution across time and space as well as aiding propagation of antibiotic resistance genes in our environment.
- How evolutionary processes affects health (Medical Geobiology): exploration of how environmental stressors influence evolution in cancer, biofilms and the thriving niches in the plastisphere.
