Retired Faculty

Prof Belal E. Baaquie

Professor Baaquie joined the Department in 1984 as a Senior Lecturer and retired as Professor on 30 June 2016.

Although his specialization is quantum field theory, Professor Baaquie has varied and multifaceted research interests. He has an abiding interest in the foundations of quantum mechanics, on which he has written a monograph; he has applied the mathematics of quantum field theory to such diverse subjects as finance, microeconomics and the modeling of human consciousness. He was actively involved in developing undergraduate pedagogy and has written two undergraduate science textbooks for non-specialists.

He is one of the pioneers in applying the quantum approach to mathematical finance and has written two books and many papers on this subject. Prof Baaquie has also proposed a statistical formulation of microeconomics that includes the theory of commodity prices, and which has been empirically tested with good results.

After retiring from NUS Prof Baaquie is taking up the position of Professor of Finance at INCEIF, The Global University of Islamic Finance, Malaysia.

Prof Baaquie was featured in the July 2013 issue of Physics Matters, the departmental biannual newsletter.

Prof Oh obtained his B.Sc. (First Class Hons) and Ph.D. in Physics in 1969 and 1972 respectively, from the University of Otago, the oldest university in New Zealand. For his Ph.D., he studied high energy physics, which relates to the study of the smallest constituents of matter, electrons, quarks etc.

Prof Oh has received various prestigious awards. These include the National Science and Technology Award (2006) administered by the Agency for Science, Technology and Research (A*STAR) which recognised Prof Oh’s outstanding contribution to themultidisciplinary field of quantum information science which has helped to position Singapore as a leader in this field. Before working on quantum information, he started his career in particle physics, particularly the Yang-Mills gauge fields, particle phenomenology and integrable models.

Prof Oh was conferred the Institute of Physics (IPS) President’s Medal in 2014.

In October 2015, Prof Oh was elected as a Fellow of the American Physical Society (APS), an honour signifying recognition by professional peers based on exceptional contributions to physics research, important physics applications, leadership in or service to physics, or significant contributions to physics education. Fellowship is limited to no more than one half of one percent of the Society's membership.

Prof Oh retired from being a CQT Principal Investigator at the end of 2014 but continues his research on quantum information, quantum computation and fundamental issues in quantum theory as a CQT Fellow.

Currently, Prof Oh is still teaching in the department.

Prof Ong Chong Kim

Prof Ong joined the Department of Physics in 1981 and retired as Professorial Fellow on 30 June 2015.

Prior to his appointment at NUS, he worked at the University of Manitoba, the Atomic Energy Research Establishment (AERE) at Harwell, UK, Ahmadu Bello University, Nigeria and Atomic Energy of Canada Limited (AECL), in Winnipeg, Canada.

Prof. Ong’s areas of expertise include computational and experimental condensed matter physics and materials physics. Highlights of his research work include his approach in the measurement of permittivity and permeability that has been well received in the scientific community. A device based on his work has now become an international standard for characterizing the dynamic properties of ferromagnetic thin films. His work has also extended into the sensitive detection and quantification of the Spin Rectification Effect (SRE ) used for spin current measurement and spin wave characterization. His achievements in the field of meta-materials include the fabrication and implementation of an omnidirectional retro-reflector, a device once deemed impossible to construct, that can reflect microwaves perfectly back to their source from all angles. This has many potential practical applications, especially in radar tracking and stealth technology.

Prof. Ong has supervised many students throughout his career. To date, 33 PhD, 34 MSc and 57 Final Year BSc students have completed theses based on research under his supervision at NUS.

Prof. Ong is a recipient of the prestigious NUS Outstanding Researcher Award, 2010. He is a Fellow of the Institute of Physics (IOP) UK and the Institute of Physics, Singapore. He served as Vice-president of the Singapore Academy of Science (1998-2000), President of the Institute of Physics, Singapore (1996-2000) and is the Founding Director of the Centre for Superconducting and Magnetic Materials(CSMM). He was Deputy Head of the Department of Physics, NUS (2006–2008). He has also served on the editorial board of three international journals.

He has co-authored more than 570 peer reviewed papers and has a H-index of 41. He also co-authored a textbook on Microwave Electronics (Wiley) and holds a patent in America.

After officially retiring from NUS Prof. Ong will take up the position of Senior Principal Research Scientist at Temasek Laboratories with a continued joint appointment at the Department of Physics to continue his work on microwave nonlinear physics and devices.

Prof Ong was featured in the July 2010 issue of Physics Matters, the departmental biannual newsletter.

Prof Tang Sing Hai

Prof Tang joined the Department of Physics as a lecturer in 1974 and retired as Professorial Fellow on 30 June 2013.

Students called him, “a dedicated teacher, initiator and a craftsman.” But Prof Tang Sing Hai is simply an unpretentious man filled with determination to go on the next phase in his life. The retired professor graduated from the class of 67 from the University of Singapore. His class is credited for producing eight PhD students of which four had the calling to teach at NUS. Among the few, Prof Tang is the last to retire after 39 years.

He pioneered innovations and initiated the laser/photonics group and research in THz materials and devices in the Department of Physics. His team was one of the most productive research groups in the department in the 1990s. Prof Tang also served as the Deputy Head of the Department of Physics for many years and under his leadership, the department reshaped postgraduate education, initiated the qualifying examination and introduced the Master of Science by coursework programmes. In the last few years as Professorial Fellow, he did an excellent job in coordinating the third year modules and handling graduation related matters.

The father of two plans to focus on sculpturing as a hobby for now. His sculptures have been displayed at exhibitions and auctions, with one of his masterpiece standing tall in front of the Department of Physics at S12.

Prof Tang was featured in the January 2010 issue of Physics Matters, the departmental biannual newsletter.

Prof Frank Watt

Prof Frank Watt joined the department of physics as a Visiting Fellow in 1990 and retired as Professorial Fellow on 30 June 2015. He was the former Director of Centre for Ion Beam Applications (CIBA).

Prof Watt was given the chance to visit NUS in 1990 under a visiting fellowship scheme operated by the International Atomic Energy Agency (IAEA) in Vienna. During that two-month visit to the Physics Department to work with the former Head of Department, Prof S M Tang, he realized that there was a high potential within NUS for carrying out interdisciplinary research (one of his research interests in Oxford was applying nuclear-physics based techniques to biomedical problems).

He subsequently took a one-year sabbatical leave from Oxford, during which time they built up a proton microscope similar to one they had designed and built in Oxford. He managed to get another three years absence of leave from Oxford, and took a further three-year contract in Singapore – during this time it became clear to him that NUS was far more interested in multidisciplinary research than the Dept of Nuclear Physics in Oxford.

He therefore gave up his tenured position in Oxford to make his stay in Singapore more permanent. This decision was encouraged by his wife and son, who love living in Singapore.
