Research Interests

My research seeks to characterise the role of free radical mediated cellular damage in disease pathogenesis and how antixoidant metabolism modulates these processes. We have focused on the macrophage-synthesised antioxidant 7,8 dihydroneopterin and how it may inhibit atherosclerosis and non-specific cellular damage during inflammation events. This work has led us to in-depth studies on the significance of protein damage and the discovery of protein hydroperoxide formation in living cells. I also have ongoing clinical studies measuring markers of oxidative damage during atherosclerosis, inflammation and diabetes.Research summary: free radical biochemistry, heart disease, the role of protein & lipid oxidation in disease pathogenesis, macrophage biochemistry and metabolism, testing novel antioxidants and radical damage in fish.
