潘国驹目前担任南洋理工大学高等研究所所长、新加坡国立大学物理系兼职教授，他也是世界科技出版集团主席及总编辑。他的专业是理论物理，研究基本粒子中的高能碰撞。曾在权威性的学术期刊发表科学论文。

美国物理学会的会士(Fellow)，人数不多，是授予对物理研究、教育以及推动科学全球化有贡献的物理学家。潘国驹1970年被当时的南洋大学黄丽松校长聘请在物理系任教，在南洋大学服务期间，组织了高能物理研究小组，并与世界顶尖大学、物理界挂钩，例如杨振宁教授及及日内瓦欧洲原子核研究中心（CERN）的Léon Van Hove等物理大师都不时常访问南洋大学。在新加坡国立大学期间，也提升了该校理论物理的研究。4年前，倡议创立了南洋理工大学高等研究所，担任首届所长，其中一项工作是每年邀请一批顶尖科学家访问新加坡，当中包括了众多诺贝尔获奖者。

潘国驹常年服务社会，担任了陈嘉庚基金主席，新加坡中国商会会长、 新中友协会长、新加坡伦敦帝国大学校友会创会会长、南洋美专副董事长以及新加坡中学理事会会长、理事等职位，并在2008年主办了华校校史展。

潘国驹也是中国多间大学的名誉教授。

Professor K K Phua is currently Founding Director of Institute of Advanced Studies at Nanyang Technological University (NTU), Adjunct Professor of the Department of Physics at National University of Singapore (NUS) and Chairman and Editor-in-Chief of World Scientific Publishing Company. Prof Phua is a theoretical high energy physicist and he did some interesting and useful work in particle physics, particularly in the field of phenomenology in high energy collisions. Many of his scientific papers were published in well-known international academic journals.

The APS Fellowship is an honor bestowed to the distinguished few physicists who have made outstanding achievements in scientific research, and may also have made significant contributions in advancing science education and promoting international collaboration. In 1970, Prof Phua was appointed by the then Nanyang University Vice-Chancellor, Professor Rayson Huang, to join its physics department. During that period, Prof Phua established the Theoretical High Energy Physics research group, thus opening up international liaison with some of the world's leading universities and physicists―such as Nobel laureate Professor C N Yang, and former Director General of CERN in Geneva, Professor Léon Van Hove―who visited Nanyang University to conduct workshops and lectures. Prof Phua also led the research of theoretical physics at the National University of Singapore (NUS), advancing it to become the main research group in NUS. Four years ago, he was invited as a Founding Director to establish Institute of Advanced Studies (IAS) as part of the research initiatives of Nanyang Technological University (NTU). One of his other main role is to invite top scientists―many of whom are Nobel laureates―to Singapore to conduct important workshops and conferences.

Professor Phua also plays an active role in serving and contributing to the society. He holds numerous key appointments―he is Chairman of Tan Kah Kee Foundation, President of Singapore-China Business Association, President of Singapore China Friendship Association, Founding President of the Imperial College Alumni Association of Singapore, Vice-Chairman of the Nanyang Academy of Fine Arts Council, and Chairman and Council Member of several junior colleges and secondary schools in Singapore. In 2008, he had organized an exhibition-forum titled "Joint Exhibition on the History of Chinese-Medium Schools in Singapore and Malaysia".
