I am a final-year PhD student in Systems Engineering & Engineering Management (SEEM) at Chinese University of Hong Kong (CUHK), where I am very fortunate to be supervised by Prof. Anthony Man-Cho So. Before that, I obtained my bachelor degree from School of Mathematical Sciences, Fudan University, advised by Prof. Rujun Jiang.
