Craig Walton – geoscientist

4th year PhD student based in the Department of Earth Sciences, at the University of Cambridge (supervised by Dr Oliver Shorttle).

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 up to chat science, and welcome email correspondence if you have an idea or any questions about my work and research topics. I can be reached at
