Our research is directed at identifying the molecules and mechanisms that govern the behaviour of lens cells of the eye, in health, ageing & disease. Our studies have identified a number of molecules, namely growth factors, that play key roles in both normal and pathological lens development and growth. Currently we are working to gain a better understanding of how these molecules function and how they are regulated in the eye. This is fundamental to identifying new therapeutics for retarding or preventing cataract, one of the most common & costly diseases of ageing.
