Biography

I earned my B.S. (2011) and Ph. D (2017) in Mechanical Engineering from Nanjing University of Aeronautics and Astronautics. During the Ph. D period, I has been an exchange student in Louisiana State University in USA for one year. I has be awarded as Alexander Von Humboldt Fellow in Technischen Universität Darmstadt (2022-2023). My research is in the area of tribology, especially in the fundamentals, evaluations, and manipulation strategies on the thermocapillary motion of liquid lubricants. Typically, I have constructed many functional surfaces (microstructure patterns, superhydrophobic or superoleophobic coatings) to regulate and control the thermal flow, established analytical models to analyze the motion, and performed corresponding CFD simulations. I have authored about 40 scientific papers, is holder of several China patents, and principal investigator of National Natural Science Foundation for Young Scientists, National Key Laboratory Foundation, Jiangsu Key Laboratory Foundation, and etc.
