I am a scientist (postdoc) in the Department of Geology and Geophysics at Yale University, where my work is funded by the NASA Astrobiology Institute. My research addresses the interactions between microorganisms and the minerals, sediments and rocks around them. These interactions have surprisingly broad implications for the history of life on Earth and the potential for finding life on Mars and other planets and moons (astrobiology).
I followed my undergraduate degree in Earth sciences from St. Edmund Hall, Oxford with a PhD at the University of Aberdeen focused on the Earth’s deep subsurface biosphere, the possibility of a deep biosphere on Mars, and the sources of methane in the martian atmosphere. My work in astrobiology has been reported by the BBC, STV, The Times, Astronomy Now, New Scientist and other TV, online and printed media. I am a Fellow of the Royal Astronomical Society and of the Geological Society of London.
