Alex Clarke-Cornwell

Lecturer in Public Health


Alex joined the University of Salford in September 2015 as a Lecturer in Public Health, having previously been a Research Fellow at the University (2008-2011).

She has a first degree in Mathematics and a Masters in Statistics; she is currently writing up her PhD, which is entitled, 'Sedentary behaviour, work and health-related outcomes: the application of empirically derived accelerometer cut-points to data from the Health Survey for England'.

Alex has been involved in a range of research projects that have used her experience of epidemiology and statistics. These include for example, studies relating to the burden of musculoskeletal disease in the UK, coding in general practice research databases, and evaluations of uptake of cardiovascular health checks in North West England. More specifically, her PhD focuses on the associations between sedentary behaviour and health-related outcomes in the workplace.

Alex has presented her research on the measurement of sedentary behaviour and physical activity from accelerometers at a number of international conferences: International Conference on Ambulatory Monitoring of Physical Activity and Movement (ICAMPAM) Limerick 2015 and Bethesda, Washington DC 2017; International Conference on Diet and Activity Methods (ICDAM) Brisbane 2015; International Society for Physical Activity and Health (ISPAH) London 2018.

She is also interested in population levels of physical behaviour and was part of a project with European colleagues as part of the consortium or the Determinants of Diet and Physical Activity (DEDIPAC) Knowledge Hub: this project used accelerometer data from national surveys to describe sedentary time and physical activity from four European countries doi:10.1007/s40279-016-0658-y

Alex is currently working on an NIHR-funded randomised controlled trial entitled, ‘The effectiveness of the SMArT Work & Life intervention for reducing sitting time in office workers’, led by Dr Charlotte Edwardson (University of Leicester). This study aims to determine the long term effectiveness of a multi-component behaviour change intervention (when provided with and without a height-adjustable desk) for reducing daily sitting time in office workers (in Leicester and Greater Manchester), when compared to no intervention.

Alex is the Deputy Lead for the Research Excellence Framework (REF) Panel for the School of Health Sciences at the University of Salford.  She is currently supervising two PhD students.


Alex is module leader for ‘Research Methods Applied to Public Health’ and ‘Epidemiology and Statistics for Public Health’; she also contributes to the ‘21st Century Global Public Health Challenges’ module.

Research Interests

Alex’s research interests include the measurement of sedentary behaviour and physical activity, determinants of sedentary behaviour, the impact of office design on physical behaviour, workplace health, and vascular health checks in the UK.
