Prof Osipowicz received his Ph.D. from the University of Göttingen, where he was a member of the group of K.P. Lieb, focusing on nuclear solid state physics, materials science and nuclear physics. He did research, both in gamma-spectroscopy of high spin states in medium mass nuclei and in Ion Beam Analysis. 

Currently, his research focuses on the development and application of ion-beam based analytical and lithographic techniques, such as High Resolution Rutherford Backscattering (RBS), Proton Induced X-ray Emission (PIXE), Elastic Recoil Detection Analysis (ERDA) and Proton Beam Writing (PBW), as well as the application of these techniques to materials science, microelectronics engineering and the life sciences. He is also Director, the Centre for Ion Beam Applications (CIBA), a multidisciplinary research centre which develops new technologies based on fast protons and ions.

Dr Lee is the Chief Radiation Physicist in the Division of Radiation Oncology and Chair of the Radiation Safety Committee at the National Cancer Centre Singapore. He holds concurrent academic appointments as Adjunct Associate Professor for Medical Physics at Nanyang Technological University (NTU) and NUS.

He serves in the Ministry of Health advisory committee on proton beam therapy. He is currently the President of the South East Asian Federation of Organisations for Medical Physics. Internationally, he has been involved in various radiation oncology medical physics projects with the International Atomic Energy Agency. He also heads the Secondary Standard Dosimetry Laboratory (Radiotherapy) for Singapore. He speaks regularly at various local, regional and international conferences.

He obtained his B.Sc. and Ph.D. degrees in Physics from NUS.

Prof Andrew A. Bettiol

Associate Professor
Department of Physics
National University of Singapore
Principal Investigator
Centre for Ion Beam Applications
National University of Singapore

Prof Bettiol was part of the team that developed the first dedicated proton beam writing beam line. He spent the last 20 years working on ion beam modification of materials, proton beam writing, photonics and super-resolution cell imaging. More recently, he secured funding to set up a new radiobiology beam-line at the Centre for Ion Beam Applications to study radiobiology and proton therapy. His current research interests include the modification of optical properties of materials by ion beams, nuclear microscopy and radiation effects in cells.

 He obtained his Ph.D. at the University of Melbourne in 1999, where he worked on materials characterisation using Ionoluminescence generated by MeV ions.

 After his Ph.D., he joined the Centre for Ion Beam Applications at NUS’ Department of Physics as a Research Fellow and subsequently as an Assistant Professor in 2007 and Associate Professor in 2014 as part of the Engineering Science programme, where he taught multidisciplinary design projects and photonics/optics to engineering science students. 

Prof Chung Keng Yeow 

Associate Professor
Department of Physics 
 National University of Singapore

Prof Chung’s research focuses on severe accidents in nuclear power plants. Using a simulation code developed in Europe, his team studied the progression of the core melt accidents from initiating events such as a station blackout and failure of some plant safety systems to the final release of radioactive nuclides to the environment. The type of nuclides, their quantities and timing of release from the reactor vessel to the containment and from the containment to the environment are estimated. These estimates are crucial in the management of these accidents.

In 2014, he joined the newly established Singapore Nuclear Research and Safety Initiative (SNRSI), a research institute which focuses its expertise in nuclear technology and safety. He was involved in setting up SNRSI’s laboratories and manpower recruitment. 

 He received his first degree in Physics from NUS in 1986. After a brief stint in junior college teaching, he took up an NUS scholarship to pursue his Ph.D. at Stanford University, where he worked under Nobel Laureate Steven Chu on using laser-cooled atoms to measure gravity. Subsequently, he did his postdoctoral training at Stanford University and Oxford University before returning to NUS’ Physics Department in 2002.

Dr Chan Taw Kuei

Department of Physics
National University of Singapore

Dr Chan is part of the team that set up and runs a Medical Physics teaching laboratory at the Department of Physics, providing hands-on training on medical imaging and radiation safety to senior students.  Over the past seven years, he has taught a postgraduate course on accelerator based materials characterisation. He also currently teaches various medical physics-related undergraduate courses and administers the Medical Physics Minor programme.

 Dr Chan graduated from NUS with a Ph.D. in Physics in 2009. He has been a lecturer at the Department of Physics since 2013.
