His research focuses on randomised controlled nutrition trials, studying the impact of various diets and supplements on chronic disease risk factors like cholesterol and inflammation. Recently, his work has evolved to explore broader motivators for dietary change, such as animal rights, climate change, and social justice, alongside a food systems approach that aims to improve food quality in institutions like universities and hospitals.
