Address:Room H710,NO.1 West Beichen Road, Chaoyang District, Beijing 100101, China
Research Interests
Our lab works on the diverse microbial defense systems, including CRISPR-Cas, prokaryotic Argonaute (pAgo), toxin-antitoxin (TA), etc., and their application in biotechnology.
1. Characterizing novel defense mechanisms and exploring the physical and functional coupling between various defense pathways, which is critical for our comprehensive understanding of microbial defense lines.
2. Exploring the defensive proteins or non-coding RNAs to develop new biotechnological tools.
3. Exploiting the defensive apparatus (like CRISPR-Cas and TA) to improve the genome editing pipelines of non-model microorganisms of industrial, environmental, or clinical importance.
2008-2014, PhD, Genetics, University of Chinese Academy of Sciences, Beijing, China.
2004-2008, Bachelor of Science, Shandong University, Jinan, China.
