Research Interests
We work in the fields of systematics, molecular phylogeography, historical biogeography, and generally on the evolution of temperate and tropical flowering plants, e.g. in families Asteraceae, Biebersteiniaceae, Brassicaceae, Fabaceae, Gentianaceae, Meliaceae, and Urticaceae (in alphabetical order). Recently, research has centered largely upon taxa of the pantropical family Meliaceae (“mahogany” family) in the order Sapindales.
