Promovendus

I work as a PhD-candidate on a research project for creating healthy and sustainable food environments in hospitals and other health care organisations. My project is part of the Regio Deal Foodvalley, where Wageningen University & Research, Utrecht University, Alliantie Voeding in de Zorg and many other organisations from the region work intensively together, to accelerate and study the transition towards more healthy and sustainable food consumption. I will defend my PhD thesis on Wednesday July 2, 2025.

I completed both my bachelor and master Nutrition and Health in Wageningen. It is a great pleasure to work as a PhD-candidate at the chair group Consumption and Healthy Lifestyles of Wageningen University & Research. My promotors are dr. Maartje Poelman and prof. dr. Emely de Vet and my copromotor is dr. Sanne Djojosoeparto, all from Wageningen University & Research.
