I started as a Chancellor's Fellow in the Physical Activity for Health group in the School of Psychological Sciences and Health in August 2015. 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 before joining the University of Strathclyde as a research associate in Jan 2014.


Has expertise in:

    • Measurement of physical activity and sedentary behaviour in children and adolescents.
    • Patterns and changes in sedentary behaviour and physical activity across childhood.

Research interests

My research interests include exploring patterns of sedentary behaviour and physical activity across childhood and adolescence and their influence on health outcomes (e.g. cardiometabolic health) and measurement of physical activity and sedentary behaviour in children and adolescents. My current fellowship program (Sitting in Teens; SITS) aims to increase the evidence base foundation for interventions aiming to decrease time spent sitting and increase breaks in sitting time in teenagers. 

I am also 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.
