Peter has published more than 130 manuscripts in peer-reviewed journals internationally. He has been awarded major competitive research grants to further study heart disease and gain a greater understanding behind blockages of the heart arteries and how best to treat these using coronary stents. He is Principal Investigator on a number of randomised clinical trials studying various types of coronary stents to treat patients with heart disease. In 2009, he was the first Australian Cardiologist to use a novel coronary imaging camera used to look within the heart arteries providing unprecedented detail about the cholesterol that causes blocked arteries and how the human body responds to having stents placed. He mentors other cardiologists across the country on how to use this technology in the catheterisation laboratory. He currently leads a busy research group examining biomedical engineering advances in heart disease and medical technologies across the Faculties of Medicine, Dentistry & Health Sciences and Engineering at the University of Melbourne.
