Plant systematics and taxonomy

My research focuses on the taxonomy, systematics, speciation, biogeography and natural history of North and South American plants using macro and micro-morphology, and molecular systematics. Currently researched groups include the flowering plant families Gentianaceae (gentians; MacrocarpaeaSymbolanthus), Brassicaceae (Parrya), Bromeliaceae (AlcantareaVriesea, and Werauhia), Loganiaceae (Bonyunia), and the fern family Ophioglossaceae (Botrychium). Geographical regions where I largely conduct my research include the Andes in South America (Venezuela, Colombia, Ecuador, Peru, and Bolivia), and Arctic and mountainous regions of North America, Europe and Asia.
