James is CMR lead at Barts Heart Centre, Medical director of Chenies Mews Imaging Centre and CEO of Mycardium AI Ltd, a UCL spinout delivering cardiovascular corelab AI analytics. Formerly, he set up and lead the Heart Hospital Imaging Centre. The centre and its affiliated CMR services are the largest in the world (28,000 scans a year).
Trained at Cambridge and Oxford, his MD at Imperial was ‘myocardial tissue characterization by CMR’. His research group have particular interests in heart muscle and conditions that affect it such as cardiomyopathy, Fabry, amyloid, valve disease, cardio-oncology, athleticism and aging which he measures using developed techniques (LGE, T1 mapping, perfusion mapping). A major current work program is measuring the heart using developed AI that exceeds human performance. He has published more than 500 papers and works inpartnership with Pharma to develop surrogate endpoints for clincical trials including first in man studies. Another interest is in making scans faster/cheaper and inimproving/maintaining quality. He set up and led the international T1 mapping development group, mrimypacemaker and CMR for lower middle income countries.
He is a former member of NICE, former President of BSCMR and a former and current board member of SCMR


Research interests:
I am interested in better understanding heart muscle diseases and linking this to therapy. I am particularly know for cardiac MRI. The 500+ papers my team and I have published focus on technical development, AI, translation, creation and standardization of new biomarkers, delivery of surrogate endpoints, defining new diseases, quality control, training, enabling others.
In 2022, I founded Mycardium AI ltd to accelerate AI delivery with a particular focus on corelab AI imaging measurement to accelerate drug development.

I was for 5 years web editor of www.scmr.org - the leading web based source of information on cardiac MRI. My team has recorded 1000s of CMR lectures over the last decade. For 10 years, I have run a visiting course fellowship for CMR. I lead a program - www.rapidcmr.com to initiate rapid CMR in LMIC countries embedded in healthcare, currently active in 10 countries. We train people in MRI for pacemakers: www.mrimypacemaker.com
