Collaboration has become the norm in scientific knowledge production. Like other forms of collaboration, research collaborations face specific problems that can jeopardize success. Together with Malte Hückstädt, Florian Meißner, and Gerhard Vowe, I conducted a study which sought to gain a deeper understanding of the relevance of different collaboration problems and the interconnections among these problems. The paper is now published in Frontiers in Research Metrics and Analytics (open access!).
