Overview

I am a mixed methods behavioural scientist specialising in the development and process evaluation of complex behavioural interventions in obesity prevention/treatment and child/family health and wellbeing. I use a wide range of methods including systematic reviews, realist evaluation, stakeholder consultation, logic model development and intervention mapping. I have worked closely with a range of stakeholders from patients, teachers, parents and children to public health practitioners, charity workers and policy makers to support their active involvement in intervention design and optimisation. I have led and supported the development and evaluation of a number of NIHR funded programmes, totalling in excess of £5 million to address childhood obesity prevention in the school setting; adult and parent carer mental health/wellbeing in the community setting and obesity treatment in the clinical setting.  I am interested in further exploring and developing new ways of conceptualising and responding to the so called ‘wicked’ public health problems of the 21st century (obesity, loss of wellbeing and health inequality) by working with multi-disciplinary teams across health and social care, education and the humanities.

I teach across a range of undergraduate and postgraduate modules, convening the undergraduate Clinical Trials and postgraduate Public Health Behaviour Change Modules. I supervise both MSc and PhD students.

 Broad research specialisms

• The development and evaluation of complex behavioural interventions to promote health using several theory-based approaches (e.g. the MRC framework for designing and evaluating complex interventions, intervention mapping and the Behaviour Change Wheel). 
• Process evaluation, including realist approaches.

Qualifications

Research

Research interests

I have a background in exercise and health psychology and specialise in the development and evaluation of complex public health interventions to address the global public health challenges of obesity, loss of wellbeing and health inequality. In order to achieve effective behaviour change, I use a wide range of methods, taking account of both individual psychosocial factors and systems theory. These include stakeholder consultation and intervention mapping to firstly understand the problem and how it might be addressed through to carrying out process evaluations and developing logic models to understand and address key uncertainties for a full evaluation.

I have a strong teaching background, having taught physical education in secondary schools for several years before lecturing in exercise and health psychology. I also have an interest, therefore, in the social and emotional development of children and improving educational attainment. I have worked with the Education Endowment Foundation to review interventions that aim to support parents’ engagement in their child’s learning resulting in national guidance.

I am interested in supervising self funded PhDs to develop interventions in complex social systems to address obesity, mental health/wellbeing/social and emotional development of children and educational attainment.
