Niklas is a postdoctoral researcher in the Adolescent Well-Being in the Digital Age programme. In his work he studies the effects of digital technology on well-being and performance using experiments, experience sampling, and large-scale data sets.

He obtained his PhD in Behavioural Science from the Behavioural Science Institute at Radboud University Nijmegen in the Netherlands. Here, he studied a similar topic, investigating whether and how permanent connectedness through smartphones affects cognitive control and well-being. He also studied the motivation behind smartphone use and tested behavioural trainings to reduce the appeal of smartphone apps.

Before his PhD, he obtained a MSc in Communication Science from the University of Amsterdam and a BA in Media and Communication and German Literature from the University of Mannheim.
