Rachelle de Vries PhD

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. 

Expertise

From 2017 to 2021, Rachelle conducted her doctoral research at Wageningen University & 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. 

Teaching

With regards to educational activities, Rachelle regularly supervises BSc and MSc student projects at Tilburg University.
