1987 the state education commission sent a delegation to study at the national Kyoto university in Japan;
1993 received a scholarship from the Ministry of Education, Culture, Sports, Science and Technology of Japan to study at the National Kochi University of Japan, and 1995 received a master's degree;
1998 received a doctorate from the National Ehime University of Japan;
Returned to China in March, 20001,and worked in the postdoctoral mobile station of Tongji University School of Transportation Engineering in February, 2002. During this period, the research on the safety evaluation of road linear structure based on ergonomics was supported by the national research start-up fund for returned overseas students, the national postdoctoral science fund (postdoctoral science fund of Ministry of Communications) and the postdoctoral research funding project of Shanghai Science and Technology Commission.
Mainly engaged in traffic ergonomics and applied technology, road traffic safety and environmental engineering, road traffic planning and design, road traffic safety improvement, traffic organization and traffic impact analysis of large-scale building facilities.
Among them, a relatively perfect experimental research system has been formed in the aspects of road alignment, road and traffic environment, and safety evaluation of traffic facilities based on ergonomics.
