The Lab

The ICETLAB is located in the Clinical Sciences Building at the Prince Charles Hospital, the largest cardiac hospital in Queensland. The laboratory is situated close to the clinical arena with only a two minute walk to surgical theatres, intensive care units and wards. This state-of-the-art research centre provides a world-class environment for medical engineering research development and commercialisation. The laboratory offers a rich suite of equipment for collaborative in-depth research including a systemic and pulmonary mock circulation loop, blood circulation loops, high performance computers, 3D printing technology and small mechanical and electrical workshops. Through our links with local universities, we have access to high end electrical and mechanical workshops (QUT, UQ and Griffith), particle image velocimetry equipment (Griffith) and a state-of-the-art Medical Engineering Research Facility (MERF – QUT) for in-vivo evaluation of medical devices. As part of the Critical Care Research Group, the ICETLAB has access to a range of biological evaluation equipment to assess the interaction between cardiovascular devices and blood. This combination of mechanical and biological research facilities and close collaboration with the clinic makes the ICETLAB an ideal facility for medical engineering research.

Prof John Fraser


Geoff was the Foundation Professor of Mechanical Engineering and is now Head of Griffith School of Engineering. He graduated his BSc(Hons) Mechanical Engineering at Nottingham Trent in 1984 and stayed on to complete a PhD in blood flow mechanics in 1988. Soon after he took up academic positions at Adelaide and then Flinders Universities. He was Chief Engineer of Ventracor Pty Ltd (1998–2004) and led a team of engineers in the development of a commercially implantable centrifugal rotary blood pump (VentrAssist) through research and into production. Geoff returned to the UK in 2004 as Associate Professor in Mechanical Engineering at Nottingham University before taking up a professorial appointment at Aston University in 2008. He came to Griffith University in 2012.

He is a professional engineer with an extensive background in research, development and translation of medical device systems, specialising in the design of implantable medical devices, particularly blood contacting devices. Geoff holds 15 patents and has 3 more provisional patents in medical devices. He is an active industry consultant, working with 5 medical device companies. He has published over 50 peer-reviewed journal articles and delivered 50 papers at engineering and medical device conferences. His has received 3 prizes for research, 2 design awards and a NATO scholarship.

Geoff’s role is a technical director to the ICETLAB and has involvement in many medical device projects and supervision of several PhD and undergraduate projects. Geoff’s lab at Griffith University’s Gold Coast campus is an extension of the ICETLAB and houses a mock circulatory loop and PIV system for measuring blood flow velocities.


John Fraser graduated from the University of Glasgow in 1991. Prior to qualification in intensive care medicine, he completed fellowships in internal medicine and anaesthesia; as well as a PhD in fetal surgery. During his NHMRC fellowship-supported PhD, he won 13 national and international research awards, and was the co-founder of the Royal Children’s Hospital Burns Research Group.

John formed the Critical Care Research Group in 2004, which has now grown from humble beginnings to become the largest group of its kind in Australasia. The CCRG is an interdisciplinary group which encompasses Intensive Care, Cardiology, Cardiac surgery, Anaesthesia, and Emergency; as well as basic science, engineering and basic animal models. The group has three purpose built labs and works in a state of the art animal research facility on transfusion models, acute lung injury, artificial heart and transplantation of heart and lung, using the ex vivo lung resuscitation device. The CCRG has produced 225 peer reviewed publications since its inception.

John’s interest in blood and ICU resulted in his PhD student Dr John Paul Tung winning the prestigious Vox Sanguinis Best Paper 2011 for his work on TRALI. He runs multiple animal, human, and secondary data analysis studies in the field of blood and critical care. He recently devised and formed a national collaborative group aimed at optimising the utilisation of blood products in cardiac surgery. He has published over 190 peer reviewed papers, received over $28 Million in research funding, and supervises 16 PhD, MPhil, and honours students. He has five children and supports Glasgow Celtic.
