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; Macrocarpaea, Symbolanthus), Brassicaceae (Parrya), Bromeliaceae (Alcantarea, Vriesea, 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.
