Research and education

I obtained my Master’s degree in 2005 at the Free University of Brussels, Belgium and later a DEA in 2007. Subsequently I stayed in Brussels to obtain a PhD in 2012 with a fellowship from the National Research Fund in Luxembourg, under the supervision of Prof. dr. Olivier Klein. I investigated the influence of environmental factors, like the size of food items, containers and portions, on food intake. Until March 2014, I worked in Tilburg as a post-doctoral fellow, again with a fellowship from the National Research Fund in Luxembourg, under the supervision of Assistant Prof. dr. Esther K. Papies. My research focused on understating and preventing the portion size effect, one of the most prevalent and powerful influences on food intake.

As of April 2014, I have been hired by the Utrecht University to work on the NUDGIS project in collaboration with Wageningen University, UniLever and FrieslandCampina. Here, I will mainly be working with Prof. dr. Denise de Ridder, Assistant Prof. dr. Marieke Adriaanse and Dr. Martijn Veltkamp. The NUDGIS project will investigate the effectiveness of nudges, defined as subtle rearrangements of a choice context that gently suggest healthier food choices. Its goal is to formulate rules to design effective nudges that help make the healthy choice the easy choice in a real-life setting. My work will focus on the role of awareness and salience in nudges’ effectiveness, their acceptability and their impact on autonomous decision-making.
