Maria Bryant
Professor of Public Health Nutrition



Maria is a nutritionist with almost 20 years’ experience in the design and delivery of trials and related methodological research in the field of diet and obesity, with a special interest in early years and childhood. In addition to her academic role at the University of York, she is the Director of Nutrition Research for Born in Bradford, the lead for Diet and Obesity evaluation for a Better Start Bradford and the evaluation Chair of ‘ActEarly’, a MRC funded project aiming to promote a healthier, happier, and fairer future for children. Maria is also the Chair of the Association for the Study of Obesity (ASO).

  • PhD Nutrition and Psychology, School of Psychology, University of Leeds
  • Fellowship of the Higher Education Academy



Maria is committed to deliver research and teaching that makes a substantial contribution to society. Her work includes a broad portfolio of obesity, food and nutrition research which spans across multiple systems.  This systems based approach is inherent in public health and nutrition research, as behaviour is influenced not only by individual psychology, biology and behaviour factors, but also by wider systems including food production and distribution, environments and social influences. 

A focus of Maria's work is with the design and delivery of evaluations for public health interventions. With this, she utilises her background in clinical trials to consider innovative methods for complex systems evaluations which are ethical and feasible, whilst ensuring minimal bias.  Her specific topic expertise is within lifestyle and non-communicable disease, particularly related to childhood obesity and dietary health. 

Maria is passionate about partnership working and is dedicated to ensuring meaningful engagement in all aspects of her work.  Thus, she always work closely with key stakeholders and beneficiaries across the life of each project and has established strong relationships with local and national government, community leaders in early years and school settings, and members of the public.
