Currently, I am working as a Research Associate in the Public Health Policy Evaluation Unit.

I have completed a NIHR School for Public Health funded PhD at Imperial. For this project, I used routinely collected data to evaluate the impact of the Healthy Start programme and the Universal Infant Free School Meal programme on purchasing, dietary and health outcomes. 

My research interests include policy evaluation, public health nutrition, nutrition welfare and school food policies, ultra-processed food and health inequalities.
