After receiving my bachelor and research master from Leiden University, I started my PhD at Utrecht University, where I studied the role of friends in the development of internalizing problems among adolescents. I was part of the team working on the InTransition project, which focused on adolescents’ development of identity and autonomy around school transitions. Using a combination of survey and observation methods, I studied both positive effects of friendship, such as the protective effects of friend support, and its negative effects, including learned negative behaviors and excessive problem-talk (also known as co-rumination). As a postdoctoral researcher on the DWELL project, I continue to study adolescent friendships, problem talk, and well-being.
