Profile:
I completed my PhD in 1992 at the University of Melbourne. I began my post-doctoral research career in the Department of Anatomy and Cell Biology and later joined the Department of Physiology. I have been awarded the Sir Colin and Lady MacKenzie Fellowship in Comparative Anatomy and been a NHMRC research fellow. My primary interest is research, and I am a Principal Research Fellow and Associate Professor. I head the Diabetes and Vascular Biology Laboratory.
Current Research Focus:
My primary focus is to understand the contribution of vasoactive and growth factor systems to the development of diabetic microvascular complications. I have a background in diabetic nephropathy, and in recent times have also become also interested in diabetic retinopathy; the major cause of blindness in the working population. In collaboration with Dr Erica Fletcher from the Department of Anatomy and Cell Biology, we are able to use a multidisciplinary approach (endocrinology, neuroscience, pathology, biochemistry, molecular biology) to investigate progressive alterations to the retinal vasculature and neuro-glia. This is possible due to the development of a unique model of diabetic retinopathy, the streptozotocin diabetic Ren-2 rat. Strong links with industry allow testing of novel pharmacological and gene therapies against specific vasoactive and growth factor pathways. My intention is to develop new, safe and effective treatment regimens for patients with diabetic retinopathy. If successful, this would be a major advance over current invasive therapies such as laser treatment.
