Current research

Phylogeny, Systematics and Taxonomy of Tillandsia, Vriesea, and Guzmania (Bromeliaceae). These three largest genera of subfam. Tillandsioideae have been intensively studied in the past decades by our research group but their phylogenies and classifications still are insufficiently resolved. Increased taxon sampling and character evaluations are needed to get better resolutions and deeper insights into the evolution of the numerous taxon groups within these genera. While molecular tools have quite rapidly developed during the past years and whole genomic analyses can now be conducted at reasonable expenses, morphological characters a still underexplored and are a major focus for the years to come.
