Johan Verjans is a Dutch cardiologist at SAHMRI Heart Health, a senior lecturer position at the University of Adelaide and is an Associate investigator of the ARC Centre of Excellence in Nanoscale Biophotonics. He is a physician-scientist combining cutting-edge research and patient care as a Cardiologist at the Royal Adelaide Hospital. During his research career (PhD Maastricht University, University of California; Post-doctoral fellow, Harvard Medical School), he has predominantly focused on translational pre-clinical and clinical imaging biomarkers using advanced invasive and non-invasive molecular imaging strategies to detect, track and predict disease at an early stage.

His recent research has focused on imaging biomarkers from large datasets using supervised and unsupervised machine learning strategies. As Deputy Director of Medical Machine Learning at the Australian Institute for Machine Learning, his main role is to connect world-class machine learning capabilities to the Biomedical Precinct in Adelaide.

He is Associate editor of the Netherlands Heart Journal, including editor of a focus issue on Machine Learning in Cardiology. He authored recently the Cardiology chapter for Springer Nature’s first book on Artificial intelligence in Medical Imaging. He is a member of the Publications Committee of the Society for Cardiovascular Magnetic Resonance. He received several young investigator awards and recently was awarded the Ahrens Researcher Award by the Australian Heart Foundation.

His Leadership capabilities were demonstrated throughout his career as chairman of the Dutch medical students, full board member of the Royal Dutch Medical Doctors Federation, National committee on the Future of Medical Education, and more recently the Chairman of Young@Heart, representing Dutch Early and Mid-career Cardiovascular Researchers on behalf of the Netherlands Heart Institute and Dutch Heart Foundation.
