Associate professor Department of Mechanical and Energy Engineering

Dr. Zhao obtained B.S. and M.S. in Mechanical Engineering, Harbin Institute of Technology in 2009 and 2011, respectively. He conducted doctoral research on precision electrical discharge machining and electrochemical machining in Precision Engineering, the University of Tokyo and obtained PhD degree in 2015. Dr. Zhao was appointed as an assistant professor of the same department right after the graduation from 2015-2018. He is currently a full member of the Japan Society for Precision Engineering (JSPE) and the Japan Society of Electrical Machining Engineers. He is the only foreign member of the Research Affiliate Committee of JSPE and has independently chaired three competitive national scientific research projects of JSPS and NSFC. He also participated in a number of projects, and undertook one major scientific research project of the Cabinet Office of Japan. He has published more than 10 journal papers while serving as a reviewer of 10 journals. He joined the mechanical and energy engineering of SUSTech in September, 2018.

With the goal of frontier applications of semiconductor manufacturing, ultimate precision optics, micro components and biomedicine, Prof. Zhao’s research team conducts innovative research in the field of advanced manufacturing such as non-traditional and ultra-precision micro machining based on basic scientific knowledge such as surface science, electrochemistry, discharge, thermal fluid mechanics and so forth.
