Me and my work

Understanding how foods make us healthy

My work involves looking at the way in which food gets into the body and what these foods do once they are inside us; I investigate how food can make us healthy and unhealthy!  

Specifically, I am interested in how food can protect our cells and our DNA, in an effort to reduce disease
