Our invited speakers include:

Andreas Holtermann

Andreas Holtermann

University of Southern Denmark

“How measure physical activity at work – different from during leisure?”

Andreas Holtermann is educated in Human Movement Science, and finalized his PhD in Health Science in 2008 from the Norwegian University of Science and Technology (NTNU), Trondheim, Norway. Since 2008, he has worked at the National Research Centre for the Working Environment, Copenhagen, Denmark, where he now holds a professor position. Andreas has published more than 200 papers in international peer reviewed journals and given numerous invited lectures at international conferences. His main field of research is on technical measurements, health effects and interventions on physical activity at work.

Sebastien Chastin

Sebastien Chastin

Glasgow Caledonian University, Scotland

“24 hours movement behaviour: Concepts, analytics and futures”

Sebastien Chastin is a Professor of Health Behavior Dynamics in the School of Health and Life Sciences at Glasgow Caledonian University and IN the Department of Movement and Sports Sciences at Ghent University. He received BSc in metrology and applied physics, Master in Applied Physics a Master in Rehabilitation Sciences and a PhD in Non-linear physics.  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.

Sophie van Belle

Sophie van Belle

Maastricht University, The Netherlands

“Modeling 24h activity patterns using random effects zero-inflated beta-binomial models”

Sophie Vanbelle is assistant professor in the department of Methodology & Statistics since 2010 (Maastricht University, The Netherlands). Her interest in reliability and validity issues grew during her Master and PhD thesis in Mathematics (University of Liège, Belgium). She was awarded a VENI grant in 2013 by The Netherlands Organisation for Scientific Research. During this grant, she developed a statistical framework to assess reliability and validity in multilevel settings. Her work permits, for example, to compare the reliability and validity of daily physical activity levels measured by an activity tracker worn on different body parts. By now, her research line moves from the field of “traditional” multilevel data to the field of intensive (spatio-)temporal data. In particular, she would like to develop a framework in which it is possible to evaluate and study real time reliability and validity levels of electronic devices like activity trackers when used in real conditions. Her work is published in top statistical journals and successfully applied in various scientific fields, including psychology and health sciences. As commitment to the statistical community, she is a scientific committee member of two major statistical conferences in 2019, associate editor of the journal Statistical Modelling and president of the Belgian branch of the International Biometric Society.

Anisoara Ionescu

Anisoara Ionescu

Ecole Polytechnique Federale De Lausanne, Switzerland

“Assessing complexity in physical behaviour: what does it tell us?

Anisoara Paraschiv-Ionescu, PhD, is a Scientist with Laboratory of Movement Analysis and Measurement at Ecole Polytechnique Federale de Lausanne (EPFL), Switzerland. She received the B.S. /M.S. and Ph.D. degrees from the Polytechnic Institute of Bucharest, Romania and the University Joseph Fourier Grenoble, France, in 1989 and 2000, respectively. Her main research focuses on biomedical signal processing with emphasis on nonlinear/complexity analysis and statistical modeling of human physical activity patterns in health and disease. She has published more than 80 scientific journals papers and conference proceedings and was involved in many national and EU projects.

Vincent van Hees

Vincent van Hees

Independent Consultant

“An open heuristic method that helped to gain new insights in human sleep”

Dr. Vincent van Hees published on various aspects of raw data accelerometry, including energy expenditure estimation, separating gravitational acceleration components, sensor calibration error reduction, methodological harmonisation challenges, activity type classification, and sleep estimation. Vincent led on the development of the popular R package GGIR, an open source tool for processing and analysing accelerometer data. Following his early experiences in epidemiological and clinical research environments, Vincent joined the Netherlands eScience Center in 2015 to advance his data science skills. As of recently, Vincent is an independent consultant combining his expertise with accelerometry, experience in the health research domain, and his data science skills to provide support to physical activity and sleep researchers with the development and implementation of analytical methods and software. Vincent holds a PhD in Epidemiology from the University of Cambridge and did his training in Engineering (Bachelor) and Human movement sciences (Master) in the Netherlands.

Martijn Spruit

CIRO, The Netherlands


Prof. Martijn Spruit (1975) is head of the research department at CIRO, a specialized pulmonary rehabilitation centre in Horn, The Netherlands. Moreover he is full professor in Rehabilitation Sciences at Maastricht University (The Netherlands) and Hasselt University (Belgium). Prof. Spruit has published >255 peer-reviewed articles on pulmonary rehabilitation, physical inactivity, and extra-pulmonary treatable traits in patients with chronic lung disease. He was the lead author on the 2013 ATS/ERS Statement on Pulmonary Rehabilitation; the European Respiratory Society awarded him the ERS COPD Research Award in 2013; and he became a Fellow of the ERS in 2016.
