Delia McCabe holds a master's in clinical psychology and a medical PhD in neuroscience, completed through the School of Medicine at the University of Adelaide. Her multidisciplinary doctorate explored the connections between psychology, neurophysiology and nutrition, and she has spent more than twenty years investigating how what we eat shapes the way the brain develops, functions and ages.A published researcher - including peer-reviewed systematic reviews on nutrition and stress - as well as an author, consultant and speaker, Delia shares her work globally, with a focus on achieving optimum brain health through lifestyle and behavioural science. She works with leaders and teams in organisations to harness and optimise cognitive potential, and is increasingly interested in how humans interact with technology. Born in South Africa and now based in Austin, Texas, she writes to make rigorous brain-and-nutrition science clear, practical and available to everyone.
