Brian Halliday is an Academic Clinical Lecturer at the National Heart and Lung Institute, based at the Cardiovascular Research Centre at the Royal Brompton Campus. He is also a sub-specialty cardiology trainee in heart failure, inherited cardiac conditions and cardiovascular magnetic resonance (CMR), completing his training in the NW London Deanery.

He completed his undergraduate training at University of Edinburgh, before moving to London to continue his clinical training. In 2015, he started a PhD at the NHLI. This included the TRED-HF trial, which set out to examine the safety and feasibility of therapy withdrawal in patients deemed to have recovered dilated cardiomyopathy. He presented the results at the Late Breaking Clinical Trial Sessions at the American Heart Association, 2018 and was primary author of the simultaneous publication in The Lancet.

He also investigated the use of CMR for the risk stratification of patients with dilated cardiomyopathy, focusing on improving the selection of patients for implantable cardioverter defibrillators. He has published articles in several high-impact journals on this topic.

He was awarded his PhD in 2018, along with the NHLI Prize for the Best Thesis. He has continued in the department as a clinical lecturer, focusing on research into dilated cardiomyopathy, myocardial recovery and metabolic dysfunction. He hopes to build expertise in clinical trials and investigate novel therapies that may help patients with dilated cardiomyopathy recover more frequently.
