Chenglong Liu got his Ph.D. from the Qingdao University of Technology in Jun. 2020. He is currently a full-time Associate Professor in mechanical engineering of the school of mechanical and automotive engineering (MAE) at Qingdao University of Technology. His main work is concentrated on theoretical and experimental study of limited lubrication. He has published 7 SCI/EI papers in peer-reviewed journals as the first author. He owns 2 invention patents in the lubrication enhancement technology. He has won the 2021 Excellent Doctoral Dissertation Award of Shandong Province.

Current research interests:

1. Theoretical and experimental research of lubrication with Limited Lubricant Supply (LLS);

2. Development of advanced industrial lubrication technology and equipment;

3. Designing and manufacturing of low energy consumption bearing.

Main Research Project:

1. 2023-2025. Mechanism and application of lubrication enhancement of composite groove array surface coupled with customized oleophilic/oleophobic pattern and bionic micro-structure.

2. 2023-2025. Mechanism and application of biomimetic micro-modeling on the surface of rolling bearings of Marine engineering equipment.
