Lili Zheng is a PhD student in Environmental Science and Engineering, University of Science and Technology Beijing, Class of 2020. She is engaged in the research of microbial water remediation and biotechnology research and development. She has participated in projects such as pollution source survey of drinking water sources in Beijing. Finally, we congratulate Dr. Zheng Lili once again and wish the graduate students of the group to keep innovating, to make further efforts and to achieve fruitful results.<\/p>\n\n\n\n
