Why I love to teach

Loading...

I am a consultant interventional cardiologist and Clinical Director of Cardiology at the Lincolnshire Heart Centre in the UK. After attending medical school in Scotland, I moved to Leicester to do postgraduate research into the aging of blood vessels in health and disease. I teach every day, and love teaching a wide variety of students in both medicine and professions allied to medicine.
