I am the Head of the Food & Nutrition National Bioscience Research Infrastructure at the Quadram, which curates and manages the food composition data of the UK diets. I have an active interest in personalized nutrition, prevention of non-communicable diseases, and the importance of the microbiome in modulating response to complex diets.

My previous work, during my PhD and post-doctoral studies, focused on understanding the molecular mechanisms leading to disease prevention (e.g. prostate cancer). As a Senior Research Scientist at the Quadram Institute I became increasingly interested the role of cruciferous-rich diets, such as those high in broccoli, in maintaining a healthy metabolism. For this, I combined human dietary intervention studies with studies on cell and animal models, using RNA sequencing of patient tissues and detailed metabolic assays.

I have always been keen in the opportunities that big data offer in maximizing our comprehension of the effect of diet and how we can translate it to population benefit.

I have been successful in securing funding from BBSRC, local charities (BigC), and US Organizations (PCF)
