Craig Walton – geoscientist

LCLU researcher in the Institute of Astronomy at the University of Cambridge. I am currently focussed on the following research projects:

  1. Building phosphate mineral texture-age records of collisional evolution in the inner Solar System
  2. Exploring the interactions between geo- and prebiotic chemistry
  3. Modelling the long-term evolution of the global phosphorus cycle

My interests span cosmochemistry, the origins of life, and global biogeochemical evolution. I am always keen to chat science. Please reach out with an email if you have any ideas or questions about my work or research topics! I can be reached at
