After graduation from his undergraduate program at Fudan University, Qing Liu started his study on nonlinear partial differential equations at the University of Tokyo and received his PhD in Mathematical Sciences in 2011. He continued his research work as a postdoctoral associate at University of Pittsburgh from 2011 to 2015. He was appointed as an assistant professor in 2015 and later promoted to associate professor at Fukuoka University. Qing joined OIST as an associate professor in 2022.
