    Professor Chen Mao was born in Chongqing, China. After receiving the B.S. degree at Wuhan University, he undertook his Ph.D. at the same place under the supervision of Prof. Lei Aiwen and Prof. Zhang Xumu. Later, he joined Prof. Stephen L Buchwald's group at MIT from 2012 to 2014. In Oct 2014, he joined Prof. Jeremiah A Johnson's group at the same place, and was promoted to research scientist in June 2016. Now, he is working as a Thousand-Talent Professor at Fudan University, and his group name is PolyMao (http://chenmaofudan.wixsite.com/polymao). The main research directions of PolyMao group include exploration of novel polymerization methodologies based on photochemistry and late transition metal catalysis; development of continuous-flow technologies to facilitate automated and efficient polymer production; design of smart materials via the combination of polymer chemistry and organic synthesis
