Currently I hold positions both of Postdoc researcher in KTH and Associate professor in Xi'an Jiaotong university. My research work is on how to control the tribological performance of engineering surface and how the surface interacts with lubricants. The aim is to solve problems and generate greater understanding relevant to a range of applications including Bio-tribology, Drag reduction & Multifunctional surface construction. Currently I have published papers over 30, such as Applied surface science, Tribology International and Carbohydrate polymers. I obtained the University excellent doctoral thesis and shaanxi province excellent doctoral thesis (2018). I was invited over 10 times' speaking. During European Advanced Materials Congress of 2018, I was selected as IAAM scientist Medal. As Principal Investigator, I hosted 10 projects including National Natural Science Foundation of China, Natural Science Fund of Shaanxi Province and China Postdoctoral Science Foundation funded project.
