My name is Desiree Lucassen and I am currently working as a PhD candidate at Wageningen University. The focus of my research is on the development of innovative tools (mainly apps) to accurately measure eating and other health related behaviours, for research purposes. I have a background in Nutrition and Dietetics and did my masters at Maastricht University on Health Education and Promotion. My main interest is in measuring and explaining eating and health behaviours in order to, eventually, influence these behaviours to promote a more healthy lifestyle. The rise of innovative technologies and sensors provides us with new opportunities to measure behaviours more accurately and with a much lower burden for participants, compared to “older” approaches. This is also in line with the view of BigO in which different (sensor) technologies are used to measure different health related behaviours of children and adolescents. Within BigO I am involved in the dissemination of the project. In close collaboration with the other partners, we communicate our progress and achievements to other audiences. My main responsibilities lie in maintaining our website and the social media channels.
