His research focuses on sports didactics, its epistemological approaches and fundamental questions of teaching. The areas of interest in the professional competences of sports teachers and university didactics, which are included in the conference theme, are also part of this context.

His research projects, which deal with the actual content of sports pedagogy (Pedagogical Content Knowledge, PCK) and teaching practice, can also be placed in this context. Methodologically, he can be categorised as a member of the Hamburg School of Casework and one of its further developments, Narrative Inquiry. He is currently on a research semester at the University of Hamburg, where he studied a long time ago as an Erasmus student.
