Sebastien Chastin

Professor Health Behaviour Dynamics of People, Places and Systems, Glasgow Caledonian University

Seb is a Professor of Health Behaviour Dynamics of people, places and systems at Glasgow Caledonian University and Ghent University. He has a background in physics and rehabilitation sciences.

He is a fellow of the Royal Statistical Society. Previously he had post at the British Antarctic Survey, Oxford and Edinburgh University. His research focusses on dynamics of health behaviour in relation to ageing, places and systems. Understanding why, when and how people decide to move or not, is crucial to promoting healthy movement behaviour and ageing.

He develops statistical and analytical techniques to extract information from body worn sensor such as accelerometers that enable to understand how humans accumulate physical activity, sedentary time and sleep and how this changes over time. Currently Sebastien has as a large portfolio of projects on the determinants of movement behaviour in older adults and clinical populations. He leads the AlphaBeT project to develop a taxomony for 24 hour movement behaviours and OpenCODA an open science project for the development of compositional analysis techniques.
