His research focuses on teacher professionalization, the structure of educational knowledge, and the relationship between science and professional practice. His methodological interests include Conceptual Systematic Reviews, qualitative and quantitative content analysis, and the combination of conceptual reconstruction with empirical studies of educational science. From January 2023 to April 2025, he led the project “Orientierungswissen für Lehrpersonen der Zukunft” (Orientational Knowledge for Teachers of the Future), funded by an Innovation Grant he had secured. His habilitation project examines how reflection and evidence can be understood as distinct but interrelated points of orientation in teacher education.
