Professor, Ph.D. supervisor. He graduated from the School of Chemistry and Chemical Engineering of Lanzhou University in 2008, and got his Ph.D. from the School of Chemistry and Molecular Engineering of Peking University (under the guidance of Professsor Zhang Jin) in 2013. In 2013-2018, he conducted postdoctoral research at Nanyang Technological University in Singapore ( under co-supervisor Professor Xiong Qihua). He won the National Research Foundation for Youth Talents of China (2018) and Program for Innovative Talents and Entrepreneurs of Jiangsu Province (2019). Since March 2018, he joined the School of Chemistry and Chemical Engineering of Nanjing University. Xu group mainly focuses on the regulation, characterization and functionality of interface interactions between nanomaterial units.
