# Tsong Yueh Chen

Tsong Yueh Chen (Chinese: 陳宗岳) is an Australian academic at the Swinburne University of Technology who is a professor and researcher in program testing and debugging. He is ranked internationally as the most prolific author in metamorphic testing.
Chen received the BSc and MPhil from The University of Hong Kong, the MSc and DIC from Imperial College London, and the PhD from The University of Melbourne under the supervision of Jean-Louis Lassez. He has an h-index of 62.
In 2021, Chen et al. were selected as the Grand Champion of the Most Influential Paper Award by the Journal of Systems and Software for their 2010 paper.
In January 2024, Chen was selected for the ACM SIGSOFT Outstanding Research Award 2024 “for contributions to software testing through the invention and development of metamorphic testing”. This award is presented to individual(s) who have made significant and lasting research contributions to the theory or practice of software engineering. As tokens of recognition, Chen was invited to give a keynote speech at the International Conference on Software Engineering in April 2024, and was interviewed by ACM SIGSOFT Software Engineering Notes after his presentation.
In December 2024, IEEE announced the election of Tsong Yueh Chen as an IEEE Fellow in the class of 2025 “for contributions to software testing through the invention of metamorphic testing and adaptive random testing”.$^{:p.6}$ Only three software engineers were elected as IEEE Fellows in the same year.$^{:pp.4,6,15}$
