NEW STAFF APPOINTMENT: KAREN SIU, PhD- Programme Manager- Medical Device Development

Dr Karen Siu obtained her PhD from Monash University in 2003 in X-ray Physics. Her postdoctoral work as an Australian Synchrotron Research Program Fellow allowed her to explore the applications of synchrotrons, or highly intense x-ray sources, to biomedical research studying cancers of the brain and breast. She focussed on synchrotron imaging for understanding the origins and development of lung disease, in particular cystic fibrosis and asthma. In her 11 years at Monash, she built multidisciplinary and international research collaborations to investigate novel methods of preclinical imaging and new measures of airway health- attracting significant funding for her research.

As a synchrotron imaging expert, Dr Siu was a key player in early studies that demonstrated the feasibility of coupling state of the art x-ray imaging with particle imaging velocimetry (PIV) techniques from fluid mechanics. These early studies on various preclinical models built the foundations of 4Dx’s patented lung imaging technology.

Before joining 4Dx, Dr Siu was User Program Coordinator at the Australian Synchrotron, which oversaw the processes by which Australian and international researchers gain access to national research infrastructure. Coupled with her previous role as Head of X-ray Imaging at Monash Biomedical Imaging, Dr Siu brings a keen interest in research management, research infrastructure and stakeholder engagement to her new role at 4Dx.

Dr Siu will oversee the company’s first FDA Premarket Notification for 4Dx’s radiotherapy devices. Successful clearance of this device will allow the company to commercially market, a key milestone for this product and for the company’s product line. Dr Siu says, “I am excited to be joining 4Dx at a time when the company is growing and maturing rapidly. It’s a thrill to be a part of the evolution of a research idea into a marketable product that will change lives”.
