Research Interests
Dr. Gregory has completed Bachelor, Masters and PhD degrees in medical engineering at Queensland University of Technology (QUT). He then completed his three year postdoctoral fellowship at the University of Queensland’s (UQ) School of Medicine which was followed by a two year research fellowship in Griffith University’s School of Engineering. During both of these fellowships, Dr Gregory was based at The Prince Charles Hospital (TPCH), where he was the Technical Director of the Innovative Cardiovascular Engineering and Research Laboratory (ICETLAB) and a Principal Research Fellow (Engineering) for the Critical Care Research Group. Dr Gregory joined the Department of Mechanical and Aerospace Engineering at Monash University in 2018, and is also a member of the Monash Institute of Medical Engineering.
Dr Gregory’s primary research focus is on the development and evaluation of cardiovascular devices, with a particular focus on rotary blood pumps. He has expertise in areas including anatomical fitting, cannula design, mock circulation loop development, physiological control, in-vitro and in-vivo evaluation of cardiovascular devices, and more. He also has some industry experience, with a three-year role as Chief Technology Officer for De Motu Cordis Pty Ltd, a medication delivery company. Some of his ongoing research projects include:
– Development of a mechanical representation of the heart and circulatory system for laboratory testing of cardiovascular devices
– Design and evaluation of a new surgical fixation mechanism for implanting mechanical circulatory and respiratory support
– Physiological control systems which automatically adjust mechanical circulatory and respiratory support performance based on patient requirements
– Improving the end-user experience by incorporating all user (patient, caregiver, doctor, etc) requirements for mechanical circulatory and respiratory support
