Alan Stitt is a Professor of Ophthalmology at Queen’s University Belfast. His research is focused on retinal diseases that are major causes of blindness worldwide. One such condition is diabetic eye disease and he is seeking to identify the cellular and molecular basis for retinal vascular pathology as diabetes progresses. Professor Stitt has been researching ways to prevent or reverse diabetic retinopathy and is particularly interested in the regenerative potential of vascular stem cells. His team is currently exploring ways to translate basic science discoveries into benefits for patients.
