Director of Science and Conservation
As Director of Science and Conservation for the National Tropical Botanical Garden, Nina oversees the strategic development of science and conservation at the Juliet Rice Wichman Botanical Research Center (BRC) at NTBG’s headquarters on Kauaʻi. Nina came to NTBG in 2019 from a position as Professor and Curator of vascular plants and Director of Science at the Natural History Museum of Denmark, University of Copenhagen, where she continues to be adjunct professor. She is also affiliated with the EECB graduate specialization at the University of Hawai‘i at Mānoa. Following her PhD from the University of Copenhagen, Nina held research fellowships at the Royal Botanic Gardens Kew in the UK and the University of Minnesota. Nina’s research is interdisciplinary and centered on the evolution and conservation of plant diversity and the relationship between people and plants.
