1993 graduated from Harbin institute of technology with a bachelor's degree in environmental engineering; 1996 graduated from harbin university of science and technology with a master's degree in thermal insulation materials and technology, and stayed as a teacher in the same year; In 2005, he received a doctorate in material physics and chemical engineering from Harbin Institute of Technology. After staying in school to teach, he taught inorganic materials analysis and testing methods, analytical chemistry, organic chemistry, inorganic materials professional English and other courses. At present, he is mainly engaged in the synthesis of inorganic photorefractive crystals and organic photorefractive materials, the analysis of structures and defects, and the research of photorefractive materials, especially holographic storage properties. In recent years, 30 academic papers have been published in well-known magazines at home and abroad, including SCI and EI 12. In 2002, he participated in the compilation of the book Introduction to Photorefractive Crystal Materials Science by Science Press, and edited the book Lithium Niobate Crystal, which will be published in 2004. During my on-the-job study, I participated in a national 973 project (research project number G 19990330) and an 863 project (project number 863200 1AA3 1304), and presided over a vertical project. In 2002, he won the second prize of provincial scientific and technological progress.
