Professor Diana Gorog is Professor of Cardiovascular Medicine at the University of Hertfordshire. She is also a Consultant Cardiologist and Clinical Lead for Research at East and North Hertfordshire NHS Trust. She also holds honorary appointments at Imperial College and Royal Brompton & Harefield NHS Trust.

Professor Gorog trained at St Bartholomew's Medical School, London, with postgraduate training at major London teaching hospitals, including the Hammersmith, Royal Brompton, St Thomas’, Royal Free and St Mary's Hospitals. During that time she obtained both a postgraduate MD (Imperial, University of London) and PhD (Kings College London, University of London) in cardiology and has continued her research interests.

She is both an academic and an interventional cardiologist, with a particular interest in thrombosis. She is actively engaged in clinical research, with a particular emphasis on identifying patients at risk of coronary and cerebrovascular thrombosis using novel near-patient testing. Projects investigating patients with coronary disease (angina, heart attack), atrial fibrillation and those undergoing aortic valve replacement are underway, and other projects involve assessing treatment with various antithrombotic medications, aiming to provide "personalised" medicine to reduce thrombosis risk, whilst avoiding bleeding in at risk individuals.

She supervises a number of higher degree students working towards MD or PhD higher degrees. She was the catalyst for setting up the MSc in Cardiology and Stroke at the University of Hertfordshire, and leads on the Cardiology aspect of this course.
