He is also actively involved in the training of nuclear medicine residents in Singapore.
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.
Prof Ng was honoured as one of the top 50 medical physicists in the world by the International Organisation of Medical Physics in 2013.
His main research contribution has been in breast imaging, in particular breast density. He has also directed research initiatives in intervention radiology, radiological safety and radiation dosimetry, and more recently, science and technology in society.
He has authored/co-authored over 230 papers in peer-reviewed journals, 30 book chapters and co-edited five books. He has presented over 500 scientific papers, at over 300 invited lectures. He has also organised and directed workshops on radiology quality assurance, digital imaging, dosimetry and scientific writing.
He is the co-founder and co-editor in chief of the Biomedical Imaging and Intervention Journal. He also serves on the editorial and advisory boards of several journals, including Medical Physics, Physics in Medicine and Biology, Singapore Medical Journal, Journal of Mechanics in Medicine and Biology, European Journal of Medical Physics, and Biomedical Physics and Engineering Express.
Prof Ng serves as an International Atomic Energy Agency consultant and a member of the International Advisory Committee of the World Health Organisation. He is also a consulting expert for the International Commission on Non-Ionising Radiation Protection. He is the Founding President and Emeritus President of the South East Asian Federation of Medical Physics and a past President of the Asia-Oceania Federation of Organisations for Medical Physics. He founded the ASEAN College of Medical Physics in 2015.
Prof Ng received his M.Sc. in Medical Physics from the University of Aberdeen and Ph.D. in Medical Physics from the University of Malaya. He is certified by the American Board of Medical Physicists..
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 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’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 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.
