My main research interests are in the field of macrosystematics of angiosperms, and flower diversity and evolution. We are in an exciting time of considerable progress in plant systematics. A new phylogenetic framework is being built by molecular systematics. This allows us to reconstruct the evolution of structural and biological features with more confidence than ever before. New clades are being found by phylogenetic techniques, and these should now be studied comparatively as to their evolutionary patterns. Additional significant sources of new data are the large number of recently discovered Cretaceous fossil flowers and the new field of Evo-Devo. A synthetic approach is required to bring these different fields together for a better understanding of the present diversity of plants on our planet.
