Dr Ian Ratcliffe is a Senior Lecturer in Science and Head of the Research Centre for Applied Science, Computing and Engineering.  He was awarded a BSc degree in Applied Chemistry from Nottingham University in 1996 and to this day remains interested in the application of chemistry to the real world. 

Ian joined the Centre for Water Soluble Polymers (CWSP) in 1999 as a Post Graduate Research Assistant prior to studying for his PhD on the Rheological Properties of Borate Cross-Linked Glucomannans. Ian has over twelve years experience of working in Research and Development within various sectors of the chemical industry and has since spent 16 years in the University sector. His post –graduate experience has been in the domain of biopolymers and this has involved  research into biofuels, biosurfactants and ‘greening’ oil recovery.

Ian started his career as a horticulturist, studying at Wye College, University of London and retains a passion for horticulture and soil science / geology. Ian was appointed as a lecturer in 2011 and is Programme Leader for Master level programmes in Formulation Science and Polymer and Biopolymer Science and supervises a number of PhD students and KTP Associates.

He also lectures in a number of Chemistry and Earth Science based modules at undergraduate level.
