Brief Bio
Professor Xie started his teaching and research career when he was awarded his PhD in 2002 at UMIST, Manchester, UK. Previously, he worked as a Research Fellow at City University of London (2003 - 2005), Research Associate at the University of Manchester (2006 - 2011), Senior Research Fellow at the University of Queensland, Australia (2011 - 2016) and Lecturer/Senior Lecturer at the University of Exeter in the UK (2016 – 2019). He also had one-year work experience in 2006 as a Senior Software Engineer of CFD at CDAJ UK Ltd. His expertise is in mathematical modelling, simulation, optimization, measurement and control in chemical engineering and minerals processing. He is a member of IChemE (the Institution of Chemical Engineers) in the United Kingdom, and a member of SME (Society for Mining Metallurgy & Exploration) in the USA.
