Hi! I am Yinfang Chen (陈胤方), a third-year Computer Science Ph.D. student “watched” by my “cornfield-watchman-professor” Tianyin Xu in the Department of Computer Science at the University of Illinois at Urbana-Champaign. I earned my Master of Computing degree from the School of Computing (SoC) of the National University of Singapore (NUS). I received my Bachelor’s degree in Computer Science at the Huazhong University of Science and Technology (HUST).

Research Interests

System Reliability, ML for System, System Security, Cloud Computing
