He received his doctorate from the Massachusetts Institute of Technology in 1991, under the direction of Gian-Carlo Rota. He is the director of the Center for Combinatorics at Nankai University.

Between 1991 and 1996, Chen was a research fellow at Los Alamos National Laboratory, working with James D. Louck. In 1996 he returned to China, founding the Center for Combinatorics at Nankai University. He also founded the Journal "Annals of Combinatorics" published by Birkhäuser. He is on the editorial board of Advances in Applied Mathematics.
