Byron is the Trial Manager for Action 3:30 - a cluster randomised feasibility study of a teaching assistant-led extra-curricular physical activity intervention in 8-10 year olds. This study is currently underway in 12 schools in the South West of England. It is funded by the NIHR-PHR Programme.

Prior to taking this post in April 2017 Byron was a Research Associate for the Sedentary theme at the Bristol Nutrition Biomedical Research Unit, managing trials and observational studies in people with type 2 diabetes. He led on PEDAL; a feasibility trial exploring the use of electrically-assisted bicycles to promote physical activity and reduce sedentary time in people with type 2 diabetes. 

Between 2011-2013 Byron coordinated the PEAR Project (Physical Environment and Activity Relationships in adolescents); a cross-sectional study in 990 adolescents exploring the complicated relationships between young people's objectively measured physical activity profiles and features of the physical and social environment.

Byron was also a young researcher with the iFamily consortium; an EC FP7 cohort study across 8 European countries. He worked alongside Professor Angie Page and Professor Ashley Cooper to deliver iFamily work package 5: "Physical activity and the environment".


Byron holds a BSc (Hon) in Sports Conditioning and Coaching from the University of the West of England, and in 2008 graduated with distinction from the University of Bristol with an MSc in Nutrition, Physical Activity and Public Health. 

Byron is a practical and conscientious study coordinator with over six years’ experience working on observational projects and interventions trials at the University of Bristol. His areas of interest include physical activity and sedentary behaviour in children and special populations, spatial mapping and mediators of health behaviours, objective measurement methods, type 2 diabetes and physical activity.

Prior to working at the University Byron assisted on the Active for Life Yr 5 project in South Gloucestershire before taking a post at the MRC Epidemiology Unit in Cambridge in 2009.  Here, Byron worked on mid-scale epidemiological studies and clinical trials which explore the genetic and environmental mediators of health outcomes, particularly indicators of type II diabetes. 

In March 2011 he joined the Exercise, Nutrition and Health Sciences Centre as full-time research assistant for the PEAR Project. He then managed a feasibility study at the Bristol Biomedical Research Unit in Nutrition, Diet and Lifestyle which explored the utility and feasibility of promoting active travel for people with type 2 diabetes through the use of electrically-assisted bicycles. 

Byron is now in post as Trial Manager (Senior Research Associate) on the Action 3:30 cluster randomised feasibility trial in the centre for Exercise, Nutrition and Health Sciences. This is a NIHR-PHR funded feasibility study of a teaching assistant-led, extracurricular physical activity intervention for 8-10 year olds.

Outside of work Byron coaches and plays Touch rugby at an international level.
