Stephen A. Rackley holds a Doctorate in Experimental Physics at the Cavendish Laboratory, University of Cambridge. He has worked for 26 years in the energy industry, with experience in some of the main technologies that are key to the currently most mature CO2 storage option - identification, assessment, monitoring and verification of sub-surface storage in the geo-sphere. More recently, his focus is on bringing significant new and evolving technologies to an advanced level (but non-specialist) student, engineering and project management audience.
