Our research encompasses a broad range of biogeographical subjects ranging from plant distributions and their geographical relationships with the environment to processes determining generation and spatial assembly of plant diversity. This includes aspects of evolution, ecology, and systematics as well as human-environment relations. Sound knowledge of basic principles of plant diversity on multiple levels, conceptual and methodological rigor in its study as well as a deep interest in plants motivate our teaching from the undergraduate to the postgraduate level.
