Dr. Junqin Shi is an Associate Professor and Ph.D. supervisor at the School of Materials Science and Engineering, Northwestern Polytechnical University. He is a specially appointed expert of the Youth Study Group of the Surface Engineering Branch of the Chinese Society of Mechanical Engineering, a young editorial board member of Nano-Micro Letters, Journal of Trilogy (Chinese and English), and the Chinese Journal of Surface Engineering, as well as an editorial board member of Scientific Reports. His research primarily focuses on friction lubrication mechanisms, surface and interface adsorption behavior, metal material deformation, and hydrogen production through water electrolysis. He is proficient in cross-scale theoretical calculations, including first-principles, molecular dynamics, and contact mechanics finite element methods, applying material genetic engineering approaches to provide microscale perspectives on surface and interface phenomena. Dr. Shi has published more than 40 papers as first author, co-author, or corresponding author in leading journals such as Nature Communications, ACS Nano, Advanced Materials, Advanced Functional Materials, Carbon, Nano Research, Tribology International, Friction, and Applied Surface Science.
