Short Bio
Chen Chen is currently a tenure-track associate professor at John Hopcroft Center for Computer Science, Shanghai Jiao Tong University, where he is also a member of the Emerging Parallel Computing Center. Prior to that, he worked as a Researcher at Huawei Hong Kong Research Center. In 2018, he obtained the Ph.D. degree in Computer Science from Hong Kong University of Science and Technology, under the supervision of Prof. Bo Li and Prof. Wei Wang. During his Ph.D. study, he visited University of Toronto for one semester (hosted by Prof. Baochun Li). He obtained the Bachelor degree in 2014 from Department of Automation, Tsinghua Univerity.
