Chris is a Professor of Isotope Geochemistry at the University of Manchester, UK. He works across disciplines in the Planetary / Deep Earth sciences, Environmental sciences and Energy / Earth sciences using inert and noble gas isotopes. His work history starts with a degree in physical chemistry at Manchester, a PhD in isotope geochemistry at Cambridge, a brief spell working in nuclear waste for the Swiss government, escape back to academia at the University of Michigan and then ETH Zurich before moving back to Manchester in 2001.
Chris has been actively involved in the organisation of the Goldschmidt conferences; he was a member of the Davos 2002 organising committee and chaired the Davos 2009 organising and science committees.
