Prof. T.H. Tse received the PhD from the London School of Economics. He is currently an Honorary Professor in Computer Science at The University of Hong Kong after retiring from his full professorship in 2014. He has been recognized internationally as the Pioneer in integrating formal and practical methods in software engineering. His present research interests are program testing and debugging. He has been ranked internationally as no. 2 among experts in metamorphic testing. Application areas of his research include object-oriented software, services computing, pervasive computing, concurrent systems, graphic applications, and numerical programs. He has more than 270 publications, including papers in IEEE TSE, IEEE TSC, Inf Sci, CACM, ICSE, and FSE, as well as a book with Cambridge University Press and a book with Wiley-IEEE Press.

Prof. Tse is an Associate Editor of IEEE Transactions on Reliability, and an Editorial Board Member of Software Testing, Verification and Reliability and Software: Practice and Experience. He has also served as Steering Committee Chair of QRS and QSIC, Steering Committee Member of COMPSAC 2002 to 2008, Program Chair of COMPSAC 2001, and Graphic Designer of FSE 2014. He was also on the Search Committee for the Editor-in-Chief of IEEE Transactions on Software Engineering in 2013. He was twice a Visiting Fellow at the University of Oxford, and was a Visiting Distinguished Scholar of the Chinese Academy of Sciences.

Prof. Tse is a Life Fellow of the British Computer Society and a Senior Life Fellow of the IEEE. He had been a Council Member of the Vocational Training Council for eight years. He was selected for a Ten Outstanding Young Persons Award, an Outstanding Disabled Person of the Year Award, and a State Science and Technology Award (recommended by the Ministry of Education, China). He was decorated with an MBE by Queen Elizabeth II of the United Kingdom.

  • Congratulations: My heartiest congratulations to Prof. Tsong Yueh ("T.Y.") CHEN, Swinburne University of Technology, for the selection by ACM for the SIGSOFT Outstanding Research Award 2024, the most prestigious award in Software Engineering.

    The Nomination: I feel humbled and honoured that ACM accepts my nomination of T.Y. for the award, "for contributions to software testing through the invention and development of metamorphic testing". I am indebted to Prof. Alastair Donaldson of Imperial College London, Prof. Rob Hierons with University of Sheffield, and Prof. Davy Towey with University of Nottingham China Campus, for their strong endorsements of my nomination.

    The Awardee: T.Y. received the M.Phil. degree from The University of Hong Kong (HKU), the M.Sc. degree and the DIC from Imperial College London, and the Ph.D. degree from The University of Melbourne. He served as an Associate Professor in HKU before migrating to Australia. He also served as the Acting Head of Computer Science for one year.

    The Achievement: T.Y. invented metamorphic testing (MT) in the late 1990s. It tackled "untestable" programs by leveraging on relations among multiple inputs and outputs. Persistent with its development, he inspired hundreds of studies by follow-up researchers. MT is currently a recognized means to enhance traditional test case generation techniques. It has evolved beyond software testing — to program proving, debugging, and numerous software engineering applications.

  • The 2010 paper titled "Adaptive Random Testing: The ART of Test Case Diversity" by Prof. Tse and team has been selected as the Grand Champion of the Most Influential Paper Award by the Journal of Systems and Software. The journal is ranked by Google Scholar as the second in h5-index among international publication venues in software systems. A retrospective of the significance and influence of the 2010 article is available in the 2021 blog post titled "Diversity, Diversity, Diversity: Three Words that Summarize the Impacts of Adaptive Random Testing", which has received 1.6K claps from supporters.

  • Prof. Tse and team proposed the innovative concept of "metamorphic robustness testing" and applied it to verify the citation indexing systems Scopus and Web of Science. The results, published in IEEE Transactions on Software Engineering and presented in ICSE 2020, revealed that the presence of hyphens in paper titles inadvertently reduces the citation counts and journal impact factors. The surprising findings attracted the attention of the international media, including ScienceAlert, Nature Index, Communications of the ACM, Psychology Today, The Australian, and Wikipedia.

  • Prof. Tse served as the intermediary of generous donations of $140 million to The University of Hong Kong for the establishment of the Tam Wing Fan Innovation Wings I and II. He is currently a Management Committee Member of the Inno Wings.

  • Prof. Tse's teacher effectiveness score at HKU in 2022/23 was 94.4%, and his course effectiveness score was 93.1%.
