Dr Cheong is part of the Division of Mathematical Sciences at NTU's School of Physical and Mathematical Sciences (SPMS), with a joint appointment in the College of Computing and Data Science (CCDS). He recently assumed the role of Assistant Dean (Continuing Education and Training) at the College of Science. Trained as a theoretical and computational scientist, his research primarily explores the interdisciplinary applications of mathematical sciences, particularly focusing on complex systems' dynamics. His notable work on Parrondo's games exemplifies how disadvantageous strategies across various domains can lead to beneficial outcomes. He employs stochastic processes, statistical analysis, and computational simulations to investigate counterintuitive behaviors in diverse systems, including physical, social, biological, and computing system. His research interests also extend to AI applications in the medical, healthcare, and education domains.

Dr Cheong received the BSC degree (Hons) in Applied Mathematics from the National University of Singapore (NUS), the postgraduate diploma in education from the National Institute of Education, and the PHD degree in Electrical and Computer Engineering from NUS. He was designated as a University Scholar with NUS. Before entering academia, Kang Hao managed a US$250M per year Academic Research Fund at the Singapore Ministry of Education. He served as an Assistant Professor in the Engineering Cluster at the Singapore Institute of Technology (SIT) from 2016 to 2018, where he received the Annual Teaching Excellence Award in 2018. Subsequently, he was an Assistant Professor at the Singapore University of Technology and Design (SUTD) from 2019 until October 2023, where he received the SUTD Annual Excellence in Teaching Award in 2022.

He is currently serving on the Editorial Board of Journal of Computational Science, Computers in Biology and Medicine, Scientific Reports, Frontiers in Human Neuroscience, Contemporary Mathematics and Games. He is recognized on the list of Top 2% in the Stanford University-Elsevier study, 2021, 2022, 2023. As an Advisor to the publisher World Scientific, Dr Cheong provides strategic guidance to enhance their publishing operations and adapt to the evolving academic landscape.
