Ir Prof. Benny C.F. Cheung is a Professor at the Department of Industrial and Systems Engineering (ISE) of The Hong Kong Polytechnic University. He obtained his Bachelor of Engineering (Hons) Degree in Manufacturing Engineering with First Class Honours from the Hong Kong Polytechnic (now The Hong Kong Polytechnic University) in 1993. After graduation, he joined ASM Assembly Automation Ltd. as a Teaching Company Associate and later as a Mechanical Engineer from 1993 to 1995. He obtained his Master of Philosophy (MPhil) degree from The Hong Kong Polytechnic University in 1996 and started his career in Precision Engineering as a Technology Development Officer in ISE from 1996 to 1998. In 2000, he obtained his Doctor of Philosophy (PhD) degree from The Hong Kong Polytechnic University and then he started his academic career as a Lecturer in ISE. He was then promoted to Assistant Professorship in 2001, Associate Professorship in 2004, and Professorship in 2012. Prof. Cheung is a Chartered Engineer (CEng), a member of The Hong Kong Institution of Engineers (MHKIE), The Institution of Engineering and Technology (MIET), The Institute of Electrical and Electronics Engineers (MIEEE), and American Society of Mechanical Engineers (MASME).
