I identify as a #research methodologist, social scientist and #Open Science advocate (habilitation in #educational science). I was co-editor of the Zeitschrift für #Bildungsforschung. I have a breadth and depth in my fields of research: from purely theoretical papers to simulation studies, from applicant faking to classroom leadership and neuromyths. At the end of the day, I want to further our understanding of substantive educational issues and of the way we create scientific knowledge.
