Yilun obtained his BEng degree in Mechanical Design from School of Mechanical Engineering, Northeastern University, China. Prior to entering Imperial, he finished a two-year MEng project related to mesh generation for finite element analysis and application at State Key Laboratory of Integrated Automation of Process Industry, Northeastern University. In the year of 2010-2011, he received his MSc degree in AME from Department of Mechanical Engineering, Imperial College. From 2011-2015, he worked on his PhD research project on the multi-scale modelling of indentation and damage, which is supervised by Professor D. Dini and Dr. D. Balint. From November 2015 to November 2016, he worked as an Early Stage Researcher, Experienced Researcher and Research Associate on the research project that predicts the surface crack behaviour under rolling contact fatigue, which was supervised by Dr. A. Kadiric. Since November 2016, he has been working as a Research Associate on the research project that solves the sliding and nano-fretting problem using a combined multi-scale coupling method, which is supervised by Professor D.Dini.
