Zhang Zhenyu is from Henan in China. He arrived in the UK from Zhengzhou Institute of Light Industry where he did his first degree in Chemical Engineering. After having achieved a distinction in the joint Birmingham/Aston University Polymer Science and Engineering Masters degree he decided to come to Sheffield to start his Ph.D. studies. We call Zhenyu "Jason", because we can pronounce that. Jason was part of the Cell-Mineral Interface consortium, and is interested in the adsorption and adhesion of extra-cellular polymers to model mineral surfaces. Molecular adhesion measurements were made using atomic force microscopy (specifically, a molecular force probe, with which he is photographed here), and adsorption measurements using a Quartz Crystal Microbalance. On Tuesday July 29, 2008 Jason successfully defended his thesis before his examiners, Dr Terry McMaster (University of Bristol) and Dr Jamie Hobbs (University of Sheffield). I was absolutely delighted that he has rejoined the group to work on the low-dimensional chemistry programme. On September 1, 2013 Jason took up a position as lecturer at the University of Strathclyde, in effect goiing home to Chemical Engineering. It is sad to lose someone so talented, but it is a privilege to see him grow as a scientist (even if he is in an Engineering Department) from his Ph.D. to becoming a successful academic. He has subsequently moved to the University of Birmingham, the University where I started research.
