Profile

Siau-Cheng Khoo is an Associate Professor in Department of Computer Science and Co-director of the NUS Business Analytics Centre. His research focuses on improving productivity of software developers, and he has expertise in both the formal and practical aspects of programming languages and software engineering. He has designed and developed static program analysis and dynamic program optimization techniques that improve programmer productivity. He has abundant knowledge in inferring of semantic attributes for code and in applying sound and optimized code search techniques. He has also applied advanced programming language theories to the design and implementation of a domain-specific language that helps investors analyze financial data. He has been doing extensive research in adapting and inventing new dynamic analyses that enable discovery of dynamic program behaviours and program bugs via data-mining techniques, which has been termed “specification mining.” His research has been published in top-tier conferences, such as OOPSLA, PLDI, ICSE, ASE, KDD, and ICDE. He has much experience in supervising graduate students and leading research projects. He has successfully completed and is working on multiple research projects funded by DSTA, MOE (Tier 1 & 2), and A*Star. Together with colleagues from NUS Business School, Siau-Cheng helped to set up the NUS Business Analytics Centre to oversee the operation of Master of Science programme in Business Analytics. The Centre was established in 2013 with close collaboration with Economic Development Board of Singapore and IBM. Its primary goal is to train Business Analysts to meet the industry need for professionals who can apply analytics technology to business problems. Siau-Cheng is currently the Co-director of the Centre.
