Professor John J Reilly
Professor of Physical Activity and Public Health Science
I joined the University in 2011 as John Anderson Research Leader and Professor of Physical Activity & Public Health Science. I was formerly Professor of Paediatric Energy Metabolism at the University of Glasgow. My research work focuses on: interventions for the prevention of child and adolescent obesity worldwide; the consequences of obesity and low physical activity in children and adolescents globally; the development and consequences of sedentary behaviour during childhood and adolescence globally; global monitoring of physical activity and sedentary behaviour in children and adolescents.
I am involved in a range of national and international Knowledge Exchange projects. Recent KE projects include
- leading the ‘Active Healthy Kids Scotland Report Card’ (www.activehealthykidsscotland.co.uk),
- international executive committee of the Active Healthy Kids Global Alliance (www.activehealthykids.org)
- membership of the Science and Evidence Group for the WHO Commission on Ending Childhood Obesity (ECHO) https://www.who.int/end-childhood-obesity/en/
- membership of the WHO Guideline Development Group on Physical Activity, Sedentary Behaviour, and Sleep for the under 5’s https://apps.who.int/iris/handle/10665/311664
- chair of the UK Health Departments physical activity guidelines update for the Under 5’s https://www.gov.uk/government/collections/physical-activity-guidelines
I have over 300 peer-reviewed papers with an h index (October 2018) of 58 (Web of Science) and 74 (Google Scholar). Recent publications include the following:

I teach on the BSc Sport & Physical Activity degree, mainly in the Physical Activity & Health classes, and supervise students doing mini-research projects in 3rd year and larger research projects in 4th year. I aim to develop an MSc in Physical Activity & Health, from 2017-2018.
My research work focuses on: interventions for the prevention of child and adolescent obesity worldwide; the consequences of obesity and low physical activity in children and adolescents (including impacts on academic attainment); the development and consequences of sedentary behaviour during childhood and adolescence in low-middle income countries as well as high income countries.
I am an editor of the journal ‘Pediatric Obesity’, and have over 200 peer-reviewed papers with an h index of 42.Recent publications include the following:
