  4. Current projects 00000 Organic geochemistry of meteorites, organic geochemistry and stable isotope geochemistry of the Permian/Triassic, Triassic/Jurassic and the “Clovis Extinction” mass extinction… Geochemical biogenicity of micro-fossils in 3.6 billion year old sediments in western Australia… Hot-spring silica organic systems particularly high altitude thermal areas in Chile where silica coats living bacteria… Other slightly more esoteric areas --- the philosophy of defining life and what can be used from knowledge gained to practical applications in the search for living organisms or past life on planets.

  5. Outreach Projects United Kingdom-European Space Settlement Design Competition Spring 2008 Sponsored by Imperial College and The Royal Society http://www.uksdc.org.uk Chair Randall S. Perry
