Supervision team

Dr. Camille Perchoux is a Research Scientist at the Luxembourg Institute of Socio-Economic Research (LISER), department of Urban Development and Mobility. She is a health geographer with a background in geography and a PhD in Public Health Epidemiology awarded in 2015 from Sorbonne University and the University of Montreal. Her research interests include the assessment of neighborhood effect on health at refined spatial and temporal scales, social and spatial inequalities in health, and longitudinal effects of environments on health. Her research involves the use interdisciplinary concepts, methods and tools from epidemiology, geography and transportation research including map-based questionnaires, GPS, (bio)sensors, mobile surveys and virtual reality technology. She is the Principal Investigator of the FragMent project.

Mrs. Noémie Topalian, M.Sc., is a PhD candidate at LISER, currently leading the research effort on the environmental determinants of momentary and daily stress. She has a Master’s degree in Applied Mathematics from the National Institute of Applied Sciences of Rouen where she specialized in the analysis of complex data structures and artificial intelligence. Noémie has worked with cohort studies at the Luxembourg Institute of Health (LIH) and has a great interest for epidemiology as well as digital health. She now wishes to put her knowledge to good use in the study of environmental determinants of health for the FragMent project.

About the FragMent project

Geographic environments, daily activities and stress: stress is nearly ubiquitous in everyday life, and act as a major risk factor of numerous mental and physical disorders. Exposures to daily environments may either act as a contributors to stress or provide some restorative qualities. For example, while greener environments reduce stress, higher built-up density and proximity to traffic do the reverse. Yet, the combination of these momentary effects on stress over a day has so far been largely ignored. This project investigates the environmental determinants of momentary, daily and chronic stress.

Your Role

In this context, the successful candidate will have the following missions:

Contribute to the research effort on the identification of vocal biomarkers of stress

FragMent aims to assess the impact of urban environment on momentary, daily and chronic stress in daily life, based on a case study in Luxembourg. To achieve this task, we make use of Geographically explicit Ecological Momentary Assessment combining GPS data with repeated assessment of participants’ momentary stress, vocal tasks, activity patterns, and environmental perceptions, four times a day over 15 days.  

The successful candidate will be expected to contribute to the FragMent project as described above and will be in charge of running analyses on the identification of vocal biomarkers of stress using machine learning methods.
