Leong Hon Wai

Leong Hon Wai is an Associate Professor at the National University of Singapore (NUS) in the Department of Computer Science under the School of Computing. He also participates in the University Scholars Programme (USP). With a Ph.D. in Computer Science from the University of Illinois at Urbana-Champaign and a B.Sc. in Mathematics (1st Class Honours) from the University of Malaya, Prof. Leong has been a cornerstone of NUS since 1987, previously serving as Division Head for Computer Science and Assistant Dean for Special Programmes. His work bridges computational theory with practical applications in bioinformatics, transportation logistics, and VLSI CAD.

Education:

• B.Sc. in Mathematics, University of Malaya (1st Class Honours)
• Ph.D. in Computer Science, University of Illinois at Urbana-Champaign

Research Interests span the design of efficient algorithms across diverse domains. Key areas include:

• Bioinformatics: Algorithmic solutions for genomic island detection, protein function prediction, and genome sorting.
• VLSI CAD: Applied research in computer-aided design for integrated circuits.
• Logistics: Algorithms for resource allocation, scheduling, and dynamic route planning.
• Computational Thinking: Pedagogical approaches to simplify complex concepts for non-computer science audiences.

His publications reflect interdisciplinary collaboration, particularly at the intersection of algorithm design and biological systems, with a focus on problems like protein function prediction and genome rearrangement. The scientific community has recognized his contributions through fellowships and teaching awards, including the Annual Teaching Excellence Award and Inspiring Mentor Award from NUS.

Awards & Honors:

• Fellow, Singapore Computer Society (2009)
• NUS Annual Teaching Excellence Award (2009)
• Inspiring Mentor Award (NUS, 2009)
• USP Teaching Award (2008)
• Best Paper Award (APCCAS-1992)
• Best Presentation Award (ICCD-1985)
• Excellent Instructor (UIUC, Spring 1985)

Teaching & Outreach initiatives include founding Singapore’s Special Programme in DISCS, pioneering NUS’s modular curriculum aligned with ACM standards, and leading the National Olympiad in Informatics (NOI) since 1998. He also co-organizes the annual 24-hour Code::XtremeApps (CXA) competition, engaging primary school students through platforms like Scratch and micro-bit. His passion for computational thinking extends to the course GET1031 for non-majors and outreach programs in K-12 education.

Professional Service includes leadership roles in the Singapore Computer Society (SCS), organizing conferences like SEARCC'99, and serving on the SCS Executive Committee (1994–2007). He is a member of prestigious societies: ACM, IEEE, and ISCB.
