 Congratulations to Professor Kingman Cheung for the  OCPA 2017 Achievement in Asia Award.

Kingman Cheung is a professor physics at the National Tsing-Hua University and currently one of Distinguished Center Scientists of the NCTS since 2015. His research focuses on the most fundamental questions in physics: the origin of mass, the unification of

all forces, the structure of space-time, and the nature of the dark matter. His research accomplishments build on his deep knowledge and extraordinary development of new physics models and determining their characteristic signatures in collider experiments.
One of the major contributions of Kingman’s work is on the understanding the origin of electroweak symmetry breaking. At the beginning of 2013 when there was the first set of Higgs boson data coming out from the LHC experiments. Kingman saw a golden opportunity to perform a global fit to all the data, because not many groups in the world can do that. Together with Jae Sik Lee of Chonnam University and Po-Yan Tseng, they constructed a framework such that the Higgs boson data can be analyzed systematically in model-independent way or in specific new models. They have successfully published the first one using the model-independent approach [1]. Subsequently, we published 6 more papers along the line in various models and data update [2-7]. Kingman received the MoST Outstanding Research Award in 2016 mainly because of this series of works.
Subsequently, more works on other aspects of the Higgs boson were studied in the past few years. One of the most important ingredients of the Higgs sector is the self coupling of the Higgs boson, which can be
probed by Higgs-pair production at the LHC. Such a possibility was explored in detail [8]. Another important parameter is the top-Yukawa coupling, both size and sign. We have shown that using the associated production of the Higgs boson with a single top quark is capable to determine the sign and the size of the top-Yukawa coupling [9]. Other interesting works include measuring the CP property of a heavy Higgs boson (if observed in the future) through its decays into ZZ or top-quark pair [10,11].  
Because of outstanding contributions by Kingman Cheung to the origin of electroweak-symmetry breaking and collider physics, he was nominated by Division of Particles and Fields of the American Physical Society, and thus honored with the Fellow of American Physical Society in 2013 with citation “For his influential contributions to collider physics in and beyond the Standard Model especially the origin of electroweak symmetry breaking”. Kingman was furthe recognized nationally and internationally: awarded the 60th MOE Academic Award by Ministry of Education in 2017 and the Achievement in Asia Award by the International Organization of Chinese Physicists and Astronomers (OCPA) in 2018.
Kingman would like to thank all the collaborators for their endless efforts to produce good research, thank colleagues and physics community for support and encouragement, thank family for countless patience and love, and especially thank God for His blessings, wisdom and love. “And we know that in all things God works for the good of those who love him, who have been called according to His purpose”
(Roman 8:28).
