In Memory of Duan Li (1952-2020)

We announce with profound sorrow that Duan Li, one of the organizers of the BFS Congress Hong Kong and a member of its Scientific Committee, passed away on Monday, November 16. A dear friend and colleague, he inspired us both professionally and personally. He made significant contributions to many fields including mathematical finance/financial engineering, optimal control and integer programming. He was a true gentleman, scholar, teacher and professional, and a dedicated and tireless worker.

Our thoughts and prayers are with Duan’s family and friends. An obituary page can be found at
