Research areas
I am interested in the origin and early evolution of life and environments on Earth and implications for the habitability of other planets. My tools include sedimentary geology, stable isotopes (carbon, nitrogen, sulphur, selenium) and transition metal geochemistry. I am also keen to apply these tools to better understand ore-forming processes through time and space.
