Hi! I’m Roelof (Anne Jelle) de Vries! Born in Amsterdam at May 21, 1985! I have a BSc in Artificial Intelligence, and an MSc in Information Sciences – Track Human Centered Multimedia (with honor), both from the University of Amsterdam. As of November 14, 2018, I also have a PhD degree from the University of Twente (my dissertation can be found here).
From October 1, 2018, I work as a postdoctoral researcher at the University of Twente in the research group Biomedical Signals and Systems. I’m involved in the Pride & Prejudice project, where I am looking into ways to tackle chronic disease prevention through careful intervention design.
From 2013 to 2017, I worked as PhD student at the University of Twente in the research group Human Media Interaction under the supervision of prof. dr. Vanessa Evers and dr. Khiet Truong. I worked for the COMMIT project called: Sensor Based Engagement for Improved Health. In this project, I mainly focused on the second work package called: Intervention Strategies for User Interaction.
In my doctoral research, I investigated how we can motivate people to inherently change their physical activity behavior through theory-based and tailored interventions in the form of motivational text messages delivered by technology. I have explored, evaluated, and documented ways in which to operationalize theory-based strategies into the form of motivational messages. Through survey studies, I have identified and evaluated characteristics of the user that can be used to tailor theory-based strategies to, and finally, I have tested and compared the theory-based motivational message interventions in a longitudinal field study.
