UK Centre for Astrobiology

McMahon Group

The McMahon Group conducts research at the interface of palaeobiology and astrobiology at the UK Centre for Astrobiology, University of Edinburgh. Through a combination of field, analytical, and experimental approaches, we aim to understand how traces of life can survive for billions of years on Earth, Mars, and beyond, and how these ancient traces can be recognised and interrogated to reveal the secrets of deep life, deep time, and deep space.
