Bio

Dr. Rachelle de Vries is a postdoctoral researcher at the Department of Communication and Cognition of Tilburg University, investigating personalized digital (just-in-time) nudges for healthy food choice. For one day a week, she is also a Lecturer-Researcher  in the field of eating behaviour and health promotion at the Consumption and Healthy Lifestyles chairgroup of Wageningen University (WUR). 

Expertise

From 2017 to 2021, Rachelle conducted her doctoral research on the existence of an automatic prioritization or “bias” in human memory for the locations of high-calorie foods, and implications of this cognitive bias for individuals’ eating behaviour (e.g. food search, food choice, BMI). Several studies from her PhD work have been highlighted by popular media outlets. Link to PhD dissertation: https://edepot.wur.nl/547038

Currently, Rachelle assesses the efficacy and underlying mechanisms of personalized novel (i.e. "just-in-time") cognitive nudges that stimulate healthy food choice in digital food environments, using various methodologies (e.g. lab and field studies). Her postdoctoral research project also aims to investigate the impact of transparency on the effects of such nudges. Furthermore at the WUR, Rachelle is working within an NWO-funded project investigating the acceptability and effectiveness of diverse health-promoting nudges (e.g. for influenza vaccination).

Teaching

With regards to educational activities, Rachelle is involved in the development and coordination of an applied data science course (Solving Societal Health Challenges with Data Science) from the new “Data Science for Food and Health” MSc program at the WUR. She regularly supervises BSc and MSc students at both Tilburg University and WUR.
