Individual Resume

Mr. Dai graduated from Nanjing Agricultural University with a bachelor’s degree in 1991, and then obtained his Master's degree and PhD from Nanjing Agricultural University (NAU).

Since his professional career at NAU started in 1991, Mr. Dai served as the lecturer at College of Veterinary Medicine from 1996 to 2002, the associate professor for College of Veterinary Medicine from 2002 to 2010, and become the professor of NAU since 2010 and a doctoral advisor. In July 2011, Mr. Dai was appointed as a Vice President of Nanjing Agricultural University.

Moreover, Prof. Dai is also the vice director of National Steering Committee of Postgraduate Education for Veterinary Medicine Degree (VMD) and the vice president of China Entry & Exit Biosecurity Society.

Research experience

Prof. Dai current research focuses on pathogenesis of bacteria, especially on Escherichia coli, which causes serious diseases both in human and animals all over the word. He leads a number of research projects funded by National Natural Science Foundation, Ministry of Science and Technology of China. His previous work includes pathogenesis, diagnosis, prevention and control of Escherichia Coli.

Current research

1)       Focusing on developing new technology for diagnosis and detection of important avian-origin pathogenic bacteria. Supported with National Key R&D Program of China (Project 2016YFD0500804)

2)       Study on the evolutionary mechanism of key biological characteristics of important infectious pathogenic bacteria. Supported by the National Basic Research Program of China (Project 973; 2015CB554200)

3)       The molecular mechanisms for sRNA-mediated regulation facilitating Avian Pathogenic Escherichia coli intracellular macrophage survival. Supported by National Natural Science Foundation of China (grant no. 31672576)

4)       The molecular mechanisms for macrophage injury induced by the critical effectors secreted from outer membrane vesicles (OMVs) of Avian Pathogenic Escherichia coli. Supported by National Natural Science Foundation of China (grant no. 31872479)

5)       Research and demonstration of animal-origin Salmonellosis prevention and control technology. Supported by Chinese Special Fund for Agro-scientific Research in the Public Interest (201403054).
