Biography

Professor Girish Dwivedi, MD, DM, MRCP (UK), PhD (UK), FESC, FASE, FSCCT, FCSANZ, is the inaugural Wesfarmers Chair in Cardiology at the Harry Perkins Institute of Medical Research, University of Western Australia (UWA), and Consultant Cardiologist at Fiona Stanley Hospital, Murdoch, Perth. He leads the "Advanced Clinical and Translational Cardiovascular Imaging" group at the Harry Perkins Institute of Medical Research (University of Western Australia) and also holds the position of Joint Head of the Cardiovascular Disease and Diabetes Program at Perkins, as well as serving as the Director of the Cardiometabolic Clinic at the Centre for Cardiometabolic Health and Research, Fiona Stanley Hospital. He has >250 manuscripts accepted or published. Several of his original research manuscripts have been published in top-tier journals such as Annals of Internal Medicine, JACC, Circulation, JACC-Imaging, and Circulation Heart Failure. He has written chapters in a highly prestigious book in Cardiology (Principles and Practice of Clinical Cardiovascular Genetics published by Oxford University Press). His group has conducted pioneering work examining the association of inflammation and atherosclerosis. He has utilized a trans-disciplinary approach that involves translational medicine and novel cardiovascular imaging methods in assessing subclinical atherosclerosis in distinct inflammatory clinical phenotypes. This body of work has received many grants and generated several publications in high-impact journals such as Annals of Internal Medicine, Chest, Journal of Nuclear Cardiology, and AJP-Heart and Circulatory Physiology. After arriving in Perth, he has collaborated closely with the Computer Science colleagues at UWA. Dr. Dwivedi started working with a MedTech start-up company based in Perth (Artrya Ltd) soon after its inception as the Chief Medical Officer and as Chief Scientific Officer (since 2021). Their joint research program is focused on the development of artificial intelligence algorithms to automate advanced and novel cardiac CT biomarker assessment towards heart disease events. Dr. Dwivedi contributed to the development of the intellectual property, resulting in a TGA approved product.
