About me

I am currently doing my PhD at the University of Twente - Telemedicine Group, externally employed as a full time Junior Researcher at Roessing Research and Development - Cluster Telemedicine. I hold a BSc. degree in Technical Computer Science, and a MSc. in Human Media Interaction (both obtained at the University of Twente). I am currently working on methods for a personalized and adaptive behaviour coach for physical activity.
