After her PhD, Helen joined Campden BRI in 2004 when she spent a year as Technical Support Officer in the Food Composition Section. The next nine years were spent in the Biochemistry Section, where Helen managed the provision of technical contract services in the area of food allergen detection, provided interpretation of testing results, consultancy, information and advice on food allergen testing.

In 2014, Helen moved to our Regulatory team where she has gained comprehensive understanding and experience of food law, not just relating to food allergens.

Helen now uses her knowledge and expertise to provide advice on all aspects of UK and harmonised EU legislation, including relating to food allergens. Helen presents on scheduled and tailored training courses on food law and food allergens, and oversees the production of our Food Law Alert.

Helen has managed various research projects; in 2023 she supervised and contributed to a Review of the literature and guidance on food allergen cleaning for the Food Standards Agency . Helen has also co-authored two guidance documents for the food industry on ‘Validation of cleaning to remove food allergens’ (Campden BRI Guideline 59) and ‘Food allergens: practical risk analysis, testing and action levels’ (Campden BRI Guideline 71).
