Malaysian Medical Physicist Bags IUPAP Young Scientist Award 2021

Associate Professor Dr Yeong Chai Hong, Associate Professor at the School of Medicine, Taylor’s University, was recently awarded the IUPAP Young Scientist Award in Medical Physics 2021, the first Malaysian scientist to win this prestigious award.

As an expert in nuclear medicine and interventional radiology, Dr Yeong, along with her research team, developed an award-winning laser-driven hot needle system for a safer and cost-effective percutaneous tissue biopsy procedure. Her innovation improves safety and minimises bleeding complications during a needle biopsy procedure. 

“To shape the future of cancer care by providing an alternative for patients, the team is currently working on upgrading the prototype so that it can be simultaneously used for tissue ablation – a minimally invasive cancer treatment,” added Dr Yeong.

According to Dr Yeong, for unresectable tumours or when patients are not fit for surgery, minimally invasive therapies such as hyperthermia therapy are recommended. Current hyperthermia therapy uses either radiofrequency, microwave, laser or extreme cold (cryoablation) energy to induce cell death at the targeted tissues, while minimising damage to the surrounding healthy tissues.

“Today, patients do not require open surgery with this innovative development and the success rate is promising. The development was created to make cancer treatment more affordable, less invasive and safer, hence improving the overall cancer survival rate and the quality-of-life of cancer patients in Malaysia,” said Dr Yeong.

This award was established and funded by the International Union of Pure and Applied Physics (IUPAP) and was awarded by the International Organisation for Medical Physics (IOMP), as the IUPAP affiliated International Commission for Medical Physics. IOMP represents over 27,000 medical physicists worldwide and 87 adhering national member organisations along with two affiliate organisations.

The award included a cash prize of 1,000 Euro, an IUPAP medal and the IOMP certificate. In addition, a short biography of Dr Yeong will be published in the e-Medical Physics World newsletter issue.

Another significant research by Dr Yeong was the development of a cost-effective and low radiation oral formulation for a whole gastrointestinal tract transit study. Clinical studies are carried out on adults and children as research has shown that the radiation dose is about 100 times lower than Computed Tomography (CT scan). In 2012, her project won the Certificate of Merit awarded by the European Society of Radiology, the second largest radiology society in the world. To date, Dr Yeong is the first and the only Malaysian who has received this prestigious award.

Dr Yeong completed the IAEA Clinical Training of Medical Physicists Specialising in Diagnostic Radiology in 2014 and was awarded the prestigious President’s Award in Research and Innovation by Taylor’s University in 2019. Dr Yeong aims to create an impact and continuity in the research industry, especially under medical physics and cancer research. 

She has published two academic books, two book chapters, 72 peer-reviewed journal papers, 16 proceedings and 7 magazine/newspaper/newsletter articles. She secured more than USD 750k research grants in total.

Currently, she is teaching the radiology module at Taylor’s University, is an invited lecturer for the Master of Medical Physics programmes at the University of Malaya, and Visiting Associate Professor for Master of Radiology programme at KPJ Healthcare University College. To date, she has supervised 54 students who graduated in PhD and Master in Medical Physics or Radiology.
