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: 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 , sedentary behaviour and sleep in children and adolescents. I have been involved in a range of national and international Knowledge Exchange projects, including the Active Healthy Kids Global Alliance www.activehealthykids.org, WHO Commission on Ending Childhood Obesity (ECHO) https://www.who.int/end-childhood-obesity/en/   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

Current Knowledge Exchange projects include:

FitBack Scotland- development of a system for national monitoring physical fitness in children and adolescents https://www.actify.org.uk/fitbackscot - Towards a Sustainable Monitoring System to Address the Physical Fitness Crisis in Scottish Children: FitBack Scotland (scottishinsight.ac.uk)

has expertise in:

• childhood obesity: aetiology; diagnosis; prevention; treatment; consequences
• objective measurement of physical activity and sedentary behaviour
• longitudinal (birth cohort) studies, in particular with ALSPAC and GMS in the UK
• systematic reviewing: evidence appraisal, and evidence - based guideline development
• Physical activity and sedentary behaviour interventions in children and adolescents

I teach on the BSc Sport & Physical Activity degree, mainly in the Physical Activity & Health classes (e.g. Sports Nutrition), and supervise students doing mini-research projects in 3^rd year and larger research dissertation projects in 4^th year.
