Personal statement

I am currently a Senior Lecturer and course leader for the BSc Sport and Physical Activity in the Physical Activity for Health group in the School of Psychological Sciences and Health. I graduated with a BSc in Biomedical Engineering in 2008, followed by a MSc in Biology of Human Performance and Health in 2009. I completed my PhD at the University of Wollongong, Australia in December 2013. I joined the University of Strathclyde as a research associate in Jan 2014 and was appointed as a Chancellor's Fellow in August 2015.


Has expertise in:

    • Measurement of 24-hour movement behaviours (physical activity, sedentary behaviour and sleep) in children and adolescents.
    • Patterns and changes in 24-hour movement behaviours across childhood.

Research interests

My research interests include examening 24-hour movement behaviours (physical activity, sedentary behaviour and sleep) in those under 18 years of age and their influence on health outcomes. In addition, I am interested in exploring novel ways to measure 24-hour movemenet behaviours in young people. My current research focussess on exploring adherence with the WHO 24-hour movement guidelines in the under 5s in several countries. I am also involved in the evaluation of a workplace health and well-being app. Last, I am part of the Gateshead Millennium Study research team. GMS is an important longitudinal study, examining changes in sitting time during childhood and adolescence, detrminants of sitting time and the association between changes in sitting time and adiposity.

Scottish Funding Council innovation application (value £59,000) involving a new cross faculty collaboration with University of Strathclyde staff from Psychology, Computer and Information Science and Physical activity for Health groups with an external Edinburgh based company called “Welbot”. Funding was awarded to assist the company to develop and evaluate a cross-platform digital wellness programme that provides tailored notifications (“nudges”) to each user, helping employees stay physically and mentally well in the workplace. The innovation of the programme is the health information which is delivered in nudges which learn and adapt dependant on the users’ actions. This project was short listed for a Scottish Knowledge Exchange Innovation of the Year Award in 2019.
