Dr. Chan worked as a software engineer and then returned to academica. He is currently an associate professor. He received all three degrees from The University of Hong Kong. His first degree was in Computer Engineering, which was quite hardware-oriented, and then he moved to the software side to study software engineering in his MPhil and PhD degrees.

Dr Chan's current research and teaching disciplines are software engineering, particularly the technical side of software engineering and its interface with emerging technologies like machine learning, blockchain, and GPU. He is interested in addressing technical challenges in program analysis and concurrency. Dr Chan published more than 100 papers in various venues such as TOSEM, TSE, TRel, TSC, TPDS, CACM, JSS, IST, STVR, SQJ, ICSE, ESCE/FSE, ASE, ISSTA, COMPSAC, QSIC, QRS, ICWS, AST, and WWW. He received the best paper awards from COMPSAC'04, COMPSAC'08, COMPSAC'10, QSIC'11, QRS'16, and ISET'18. He was one of the awardees of the CityU President's Awards 2017. His published work can be found at his CityU Scholar page or his Google Scholar page. Preprints of articles can also be found on his website or obtained from him on request.

Dr Chan is on the editorial board of the Journal of Systems and Software, Software Testing, Verification and Reliability, Array, and the International Journal of Creative Computing. He is serving or has served as PC member of some conferences such as ICSE, ESEC/FSE, ISSTA, ASE, COMPSAC, QRS, AST, MM, ICMR, ICWS, and ICSOC.
