QualificationsBSc(Cant), PhD(Otago)
Research summaryEpigenetics; gene structure and function

Research

Many environmental factors including diet can influence the pattern of chemical modifications on our DNA (epigenetic marks). Dr Aaron Stevens is investigating whether nutritional supplementation with micronutrients can influence patterns of DNA methylation in the human genome.
