Being Interested In Both The Intensive Monitoring Of Physical Activity Behavior And Climate Change Mitigation: Some Propositions For Managing Cognitive Dissonance

Wednesday, June 19 4:30-5:30pm


Guillaume Chevance is an interdisciplinary researcher with a first MSc in Sport Sciences, a second in Health Psychology, and a Ph.D. in Human Movement Sciences from the University of Montpellier (France). At the beginning of his research journey, he studied motivation towards health-related behaviours. He then completed a postdoc at the University of California San Diego (US) with a team interested in the design of digital behaviour change interventions.

Guillaume is mainly interested in the dynamics of health behaviour change, such as physical activity, eating behaviors, and sleep, in a context of climate change mitigation and adaptation. For that purpose, he uses digital technologies and related methods to better understand what is going on in our daily lives. He is currently Assistant Professor at the Barcelona Institute for Global Health, ISGlobal, where he leads the eHealth group.

He has been leading the World Playground Research Institute since 2022. He has an MSc degree in Forest and Nature Management from Wageningen University, The Netherlands, and a PhD degree in Greenspace Management from the University of Copenhagen, Denmark.

His research interests revolve around three main topics: playgrounds, conducting multi-disciplinary intervention studies to create active living environments, and developing tools and methods that make it possible to measure active living and the environment it takes place in. Jasper has contributed to over 150 peer-reviewed articles and was President of the International Society for Physical Activity and Health (ISPAH) from 2020-2022. Providing guidance and support for PhD students working with device-based data on physical activity behaviour is an important part of his job.

Kim Meredith-Jones

University of Otago

The Past, Present, And Future Of Sleep Assessment And Monitoring

Friday, June 21 8:30-9:30am


Kim Meredith-Jones, an Associate Professor at the University of Otago, (New Zealand), specializes in evaluating 24-hour movement patterns, particularly focusing on objective sleep assessment. Leading major research projects involving over 2000 participants, she has played a pivotal role in assessing physical activity and sleep.

As an invited member of academic panels, Kim contributed to both the 2018 and 2022 NZ Physical Activity Report Cards for Children and Youth, including contributions to assessing sleep patterns in NZ children. Her expertise also extends to consulting on optimal measurement methods for sleep across a wide range of randomized controlled trials, including studies on movement behaviours in infants and toddlers and the effects of probiotics on sleep and gut health in adults. Kim is recognized as an authority in her field, having been an invited speaker at prestigious events like ISBNPA 2019, INTUE 2019, and Sleep in Aotearoa 2021 and 2023.

Invited Speakers

Örjan Ekblom

The Swedish School of Sport and Health Sciences


Wednesday, June 19 2:00-3:00pm


Örjan Ekblom is a professor at the Swedish School of Sports and Health Sciences in Stockholm, Sweden. His research areas are acute physiological and psychological effects of physical activity, as well as epidemiological studies on relations between physical activity indices and health-related variables across ages. Using genetically informed designs, we try to shed light on potential causal relations.  In previous and ongoing studies, we have focused on relationship between physical activity and brain health, i.e. mental health and cognitive abilities in healthy populations and among individuals with dementia, depression, anxiety, and first-episode psychosis.

Séverine Sabia

National Institute of Health and Medical Science (Inserm U1153), and University College London

Physical activity and sedentary behavior patterns in old age: their determinants and impact on cardiovascular disease and mortality

Wednesday, June 19 2:00-3:00pm


Séverine Sabia is a research professor in epidemiology at the National Institute of Health and Medical Science (Inserm) in France. Her main research domain is on health behaviours, including physical activity and sleep, with a particular interest in methodology. She set up the Whitehall II accelerometer study in 2012 and has led the methodological and substantive research to study the role of objectively measured physical activity and sleep for ageing outcomes. She is a contributor of the GGIR R package for analyses of raw accelerometer. She now leads a project on circadian rhythm and dementia using data from a general population and memory centre patients, funded by the European Commission.

Early Career Invited Speakers

Boris Cheval

École normale supérieure de Rennes

Uncovering the neuropsychological barriers to physical activity behavior

FRIday, June 21 11:45am-12:45pm


Professor Boris Cheval’s research focuses on understanding the socio-economic and neuro-behavioral mechanisms that drive physical activity behaviors to improve health. He is the author of more than 100 articles and one book, all of which have made significant contributions to these areas of study.

After completing his initial academic training in France in the field of exercise and sport sciences, he embarked on a postdoctoral research position in the Methodology and Data Analysis Group (University of Geneva) to further develop his statistical expertise. During subsequent postdoctoral positions at the University Hospitals of Geneva and the Swiss National Center of Competence in Research LIVES, he deepened his investigations on physical activity, with a particular focus on health and socioeconomic inequalities.

In 2019, Dr. Cheval received a competitive grant from the Swiss National Science Foundation (SNSF) to advance his research at the Swiss Center for Affective Sciences (University of Geneva). In 2023, he joined the École normale supérieure de Rennes as an associate professor. Here, he continue his research on the neuropsychological factors influencing physical activity, while training students in research methods in the humanities and social sciences. He has received a Chaire de Recherche Rennes Métropole to study the neurobiological mechanisms that underlie affective response during physical effort.
