My research at the University of Edinburgh’s UK Centre for Astrobiology explores how rocks, minerals and sediments on Earth and Mars can select, shape and sustain communities of organisms, and how organisms in turn produce, degrade and modify rocks and minerals to leave lasting traces. I use experimental, analytical and field-based techniques, and publish in a wide range of journals.

Active research questions include:
- How do fossils from Earth inform the search for past or present life on Mars?
- How do microorganisms like bacteria become fossilised, and how much palaeobiologically valuable information is preserved?
- How would microorganisms fossilise on Mars?
- How good is the fossil and geochemical record of the “deep biosphere”?
- How did microorganisms in sediments and microbial mats influence fossilisation processes in exceptionally preserved fossil assemblages from the Ediacaran and other periods?
