Dr Marshall studied medicine at Downing College, Cambridge and Cambridge University Medical School, qualifying with an additional intercalated honours degree in Medical Sciences (Neuroscience). Following general professional training and a period of study overseas in New Zealand, his specialist training was undertaken in the North West Thames region, including a research post based at the Royal Brompton and Harefield NHS Trust which culminated in the award of a Medical Doctorate (MD) from the University of Cambridge in 2013. He subsequently undertook a sub-specialty training fellowship in advanced cardiac imaging at Harefield Hospital. He has accreditation in both Cardiology and General Internal Medicine.

He has published research papers on the prognostic value of exercise capacity in IHD, and the role of echocardiography and radionuclide (nuclear) imaging in heart failure patients undergoing implantable device therapy. He is accredited in echocardiography and cardiac CT imaging; he has gained US Board Certification in Nuclear Cardiology, and is trained in cardiac magnetic resonance (CMR) imaging.
