1987 was assigned to Shenyang Pharmaceutical University after graduation, and has been engaged in analytical chemistry teaching and scientific research. In June, 2003, he received his doctorate in pharmaceutical analysis from Shenyang Pharmaceutical University. The theory and technology of quantitative control of fingerprint of traditional Chinese medicine were established, which promoted its wide application. Through 46 quantitative parameters, the quality characteristics represented by the fingerprint of traditional Chinese medicine are revealed, and the information quality control technology of traditional Chinese medicine is established. In 2006-2008, when he was in charge of the major research project of the National Natural Science Foundation, he cooperated with the whole research group and initially established the grid artificial intelligence platform (including 8 online sub-expert systems) of the online expert system of fingerprint of traditional Chinese medicine with independent intellectual property rights in China. Since 200 1, 24 graduates and 30 graduate students have been trained. Main business 1. Fingerprint and its informatics research (including high performance liquid chromatography, gas chromatography and HPCE); 2. Basic theory, method and application research of TCM fingerprint: 3. Research on online expert system of TCM fingerprint: 4. Application research of capillary electrophoresis and microfluidic chip in pharmaceutical analysis (focusing on the application of capillary electrophoresis and microfluidic chip in TCM fingerprint); 5. Research on new technologies and methods of chromatography; 6. Study on protein's omics and drug quality control. More than 80 academic papers/kloc-0 were published at home and abroad, and 5 papers were included in SCI.
