Technical broker of Qingdao science and Technology Bureau, peer review expert of mechanical discipline project of National Natural Science Foundation of China, and communication review expert of dissertations of the Ministry of education. Academically, I am mainly engaged in the numerical theoretical calculation of tribology, the application basic research of advanced lubrication technology, and the development of tribological measuring instruments. In March 2014, I was sent by the Ministry of science and technology to visit Brno University of technology in the Czech Republic. In November 2016, I participated in the China Japan Cherry Blossom plan to visit Kyushu University of technology in Japan. 30 academic papers were published in tribology international, industrial lubrication and tribology, Journal of internal combustion engine, Journal of tribology and other first-class journals, of which 10 were retrieved by SCI and EI. As the project leader, I presided over the National Natural Science Foundation of China, the research fund for innovation and entrepreneurship education reform of Chinese universities, the general research project of Humanities and social sciences of the Ministry of education, the R & D and innovation plan project of agricultural machinery and equipment in Shandong Province, the key R & D plan (public welfare special) project of Shandong Province, the general project of Shandong natural science foundation and the collaborative education project of the Ministry of education, and participated in 4 projects of the National Natural Science Foundation of China. In addition, I presided over 1 popular science project in Qingdao, 1 famous school project and 7 school level teaching and research topics. I have guided students to win 6 national competitions and more than 60 provincial competitions. The students have won awards such as the star of self-improvement of Chinese college students, Baosteel scholarship, national scholarship and good young people in Shandong in the new era.
