I mainly engaged in researches on the development of new technology for surface strengthening of materials, metal additive manufacturing, advanced material forming and connection technology. I presided over and participated in more than 10 various scientific research projects at the national, provincial and ministerial levels, including one project from the National Natural Science Foundation of China and one project from the Science and Technology Development Plan of Jilin Province for which I was the project leader. As the first responsible author, I have published over 20 SCI/EI papers, including papers on Applied Surface Science, Materials Science and Engineering A, Journal of Materials Processing Technology and other high-level international authoritative academic journals. As a main participant, I have applied for over 10 national invention patents among which four patents have been authorized. As the main participant, I won one first prize of the National Commercial Science and Technology Progress Award and one second prize of the Jilin Provincial Science and Technology Progress Award.
