Mainly teaching zoology, biochemistry, introduction to bioengineering, progress of life science and other courses. The main research fields involve zoology (entomology), biochemistry, biological resources development and many other fields. As the main researcher, he participated in several national natural science foundation projects, national 863 fund projects and key projects of Sichuan Provincial Department of Education, and made in-depth research on the economic characteristics of important resource insects-Cerasus, the faunal distribution of parasitic flies in Sichuan and Chongqing, rodents and endophytes in Sichuan hilly areas. In particular, important progress has been made in the study of insecticidal active components of toxic plants Eupatorium adenophorum and Eupatorium adenophorum, which laid a good foundation for the development and utilization of high-efficiency and low-residue botanical pesticides. The research results of endophytic bacteria and active substances hosted by him are in an absolute leading position in the research of endophytic bacteria in China. He has published more than 20 papers in Journal of Microbiology, High-tech Communication, Journal of Plant Protection, Journal of Applied and Environmental Biology, Plant Protection, Zoological Research, China Pharmaceutical Journal and Journal of Sichuan Normal University.
