Clare is a Lecturer in Behavioural Obesity Research at UCL’s Health Behaviour Research Centre, where she leads the Obesity Research Group. She is also an honorary Research Fellow at Liverpool University. After an initial career in the pharmaceutical industry, Clare retrained as a Psychologist, undertaking an MSc and PhD at UCL, and post-doctoral training at UCL and King’s College London. Her research interest is understanding how genes and the environment interact to determine variation in early weight gain, with a focus on appetite regulation and eating behaviour. In 2007, with Professor Jane Wardle she established Gemini, the largest population-based birth cohort of twins ever set up to study genetic and environmental contributions to early life growth. Clare currently leads the Gemini study. She is also an elected Trustee for the UK Association for the Study of Obesity, and recently established their first London Regional Group.
