Zhaojun

I graduated from Jilin University (the largest university in China) with a Ph.D. under the Professor Zhao Ji, a famous scientist in the manufacturing field, the former president of Northeastern University, and the chief scientist of China's key R&D program. The goal is obtained high surface accuracy, low surface roughness, and low machining damage and I have been engaging in soft abrasive flow polishing, optical rheological high-profile low-damage polishing, ultrasonic-assisted multi-field maching and polishing.

In recent years, I have presided over 2 Chinese national fund projects, 1 Zhejiang Province fund project, and many projects entrusted by enterprises. Additionally, I Have participated in 4 national level research projects, 2 provincial and ministerial level projects, more than 10 enterprise entrusted projects. The total amount of the contract of that projects is more than 10 million yuan. More than 20 papers (cited more than 180 times) have been published. As the first author, I have won 2 ESI highly cited papers and 1 hot paper. Up to now I have obtained more than 70 authorized Chinese national patents.

Currently, I am a senior member of the Chinese Mechanical Engineering Society, a senior member of the Zhejiang Institute of Vibration Engineering, a communication review expert of the National Natural Science Foundation of China, a review expert of the Natural Science Foundation of Guangdong Province, and a talent review expert of Guangdong Province. I have been reviewer serving as Journal of Material Processing Technology, Journal of Manufacturing Processes, International Journal of Precision Engineering and Manufacturing, Precision Engineering and other 14 renowned international journal.
