James has been a mainstay at ߲Ƶ, having completed his BSc (Human Biology), MSc (Physical activity and public health) and PhD (Digital Health) at ߲Ƶ. Following on from his PhD, James undertook an Enterprise Associate position with Dr Dale Esliger, working primarily with external commercial companies on various research projects relating to the quantification of human behaviour. Between September 2019 and November 2020, James was working as a Senior Research Associate on the NIHR funded Snacktivity project with Professor Amanda Daley. Since then James has been interested in the use of machine learning and AI to develop digital health interventions to increase participation in physical activity as part of the Centre for Lifestyle Medicine and Behaviour in Digital Health.
James’s research focus is on two main areas. The first involves testing the accuracy and reliability of mHealth technologies to measure a variety of metrics. The second research area focuses on the design and implementation of digital health behaviour change interventions in inactive adult populations. These interventions may include the use of novel mHealth technologies or methodologies to help participants to become more active more often. Specifically, James is interested in using Artificial Intelligence and Machine Learning to develop Digital Health interventions to increase participation in physical activity.
James has also worked extensively with commercial organisations in the past and has a strong interest in bridging the gap between academia and industry.
