Research interests

My main research interests are related to diversification and reticulate evolution in the European members of Gentianella section Gentianella and in conservation of these biennial taxa that suffer from severe habitat loss. Another focus of my research concerns evolution and vegetation dynamics on oceanic islands and the impact of alien biota on such islands. I am also interested in the ecology and reproduction of endemic taxa of the Austrian flora.
