About me
I am assistant professor at the Games for Emotional and Mental Health Lab and the department of Developmental Psychopathology. I have a cross-disciplinary background and received both my B.Sc. and M.Sc. in Applied Mathematics from Delft University of Technology, where I later also held my first postdoc postdoc position in Affective Computing. I received my Ph.D. in Experimental Psychology from the University of Cincinnati, OH. My research interests include nonlinear dynamical systems modelling, applied games, and behavioural and clinical change processes. My specific focus is on the analysis of in-game behaviour and physiological states towards real-time personalization of game interventions for children and adolescents with mental health problems (work that is supported by a ZonMw Off-Road grant). I am involved in many of the GEMH Lab projects and the daily supervision of several of its students.

Exploring the Potential of Game-based Biofeedback for Anxiety Regulation
About the projectThis project explored the potential of using game-based biofeedback interventions for anxiety regulation. Specifically, the project had the following aims: 1) Creating a new integrative theoretical model featuring traditional as well as newly proposed mechanisms of change in biofeedback interventions for anxiety regulation. 2) Further developing and validating the efficacy of the biofeedback video game DEEP as an anxiety regulation tool. 3) Formulating guidelines for future research and development of biofeedback interventions for anxiety regulation.

Reducing Stress Through Virtual Social Support
About the projectPeople with large social networks on average live longer, happier, less stressed lives. We can potentially leverage video games and virtual spaces to increase the experience of social support and impact daily stress and anxiety. Therefore, this project aims to show that virtual social support can lower stress, and potentially impact stress coping behaviours.
