Dr McDonald’s research focuses on developing strategies to preserve normal vasculature and prevent vascular diseases caused by diabetes and aging, with a particular interest in oxidative stress and its impact on vascular growth/function/recovery and tissue repair.

More specifically, her group focuses on:

• Vascular Biology and Cell-Cell Communication: Endothelial / Mural (Pericyte and Smooth Muscle)/ Microglial Cell cross talk; 
• Signalling Pathways:  Nitric oxide Synthases (NOS); NADPH oxidase; Reactive Oxygen and Nitrogen Species (ROS/RNS); Notch/Delta (Dll), Hypoxia; Hyperoxia and Inflammation
