The CIRCLES study


Investigating the health benefits of blueberries

(L-R) Corbin, Vera, Peter and Lindsey. 

The CIRCLES study is led by Professor Aedin Cassidy, Professor of Nutrition at Norwich Medical School, at the University of East Anglia. As the CIRCLES study chief investigator, Professor Cassidy has intellectual, administrative and ethical responsibility for the research project. 

The day-to-day running of the project is coordinated by Dr Peter Curtis, supported by Dr Lindsey Berends and Dr Vera van der Velpen. Research assistance is provided by Corbin Griffen and visiting students. Our study receives nursing support from Kerrie Self and Judith Gowlett and administrative expertise are provided by Tim Greene.

In addition to the ‘day-to-day’ team, our study benefits from extensive support from clinical and academic colleagues at the Norwich Medical School (UEA) and Faculty of Medicine and Health Sciences, as well as clinical colleagues within the Norfolk and Norwich University Hospital (NNUH). The study is also supported by the UK Clinical Research Network (UKCRN), in the Diabetes, Metabolic and Endocrine disorders division and the Norfolk & Suffolk Primary and Community Care research office (South Norfolk CCG) and participating General Practitioners (GPs) within these areas.

From all of the team, we would like to extend an invitation to take part in our research and would like to thank you for your time and consideration.
