Dr Zhihua Xie took up his lectureship in the School of Engineering at Cardiff University in January 2017 from Imperial College London. He obtained Ph.D. in Computational Fluid Dynamics (CFD) in 2010 from the University of Leeds, funded by the Marie Curie EST Fellowship. He worked as a research associate in computational hydraulics at Cardiff University from 2010 to 2012 and a research associate in numerical modelling of multiphase flows on the EPSRC MEMPHIS Programme Grant (www.memphis-multiphase.org) at Imperial College London between 2013 and 2016. His main research interest is in developing CFD codes for predicting interfacial and multiphase flows in environmental and industrial problems. His research is funded by EPSRC and Newton Fund (via British Council). He is a member of EPSRC Peer Review Full College, a review panel member for British Council, and a active reviewer for several leading international journals.
