David H. Lorence
- Director of Science and Conservation
Dr. David Lorence occupies the B. Evans Chair of Botany and came to the National Tropical Botanical Garden in 1987. Research specialties are systematic studies of tropical plants, floristics, and invasive plant species. His systematic research focuses on Pacific and neotropical members of the large and diverse Rubiaceae family, which includes coffee, quinine, and gardenias. He also studies Pacific island pteridophytes and the Monimiaceae family of the Malagasy region.
Timothy W. Flynn
- Herbarium Collections Manager
Tim is Collections Manager of the Herbarium PTBG at the National Tropical Botanical Garden. He has been working at NTBG since 1981. In addition to managing the herbarium he has also participated in fieldwork in Hawaiʻi, Samoa, Tonga, Niue, the Cook Islands, Kosrae, Pohnpei, Palau, Australia, New Caledonia, and Ecuador.
Seana K. Walsh
- Conservation Biologist
As Conservation Biologist of the National Tropical Botanical Garden, Seana’s primary role is to lead in the development of the organization’s activities to implement the Hawaiʻi Strategy for Plant Conservation. She earned a Master’s degree in Botany from the University of Hawaiʻi at Manoa. Her applied research interests include plant breeding systems, pollination ecology, and population genetics.
Kenneth R. Wood
- Research Biologist
Ken’s research focuses on the study and conservation of Pacific Island floras. His essential responsibilities include organizing and conducting botanical field surveys with a specialty in accessing rough terrain habitats. Other aspects of his research include: mapping the distribution and abundance of rare Pacific island plants (phytogeography); collecting herbarium specimens for scientific study, collecting seeds, spores, and cuttings for conservation, and DNA material for genetic sequencing; publishing conservation status data and new species descriptions; and contributing to conservation biology research and educational outreach through national and international scientific collaboration.
- Seed Bank & Laboratory Manager
As Seed Bank and Laboratory Manager at the National Tropical Botanical Garden, Dustin specialize in ex situ seed conservation biology with an emphasis on seed and pollen storage behavior, seed longevity and aging kinetics, seed borne pathogen abatement, and seed dormancy and dormancy alleviation of native Hawaiian plant species of conservation importance. His research aims to understand how seeds respond to desiccation and subfreezing temperatures, identifying regeneration intervals, and determining optimal seed propagation techniques.
- Science and Conservation Specialist
Margaret came to the Science & Conservation Department at NTBG in 2006, after receiving her JD and Master of Law degrees from the University of Washington, as well as graduate certificates in Conservation Biology Policy as well as Patent and Intellectual Property Law and Practice. While at NTBG she facilitated and wrote a Collections Policy, and currently researches and compiles reports on rare plants for US Fish and Wildlife Service and the International Union for the Conservation of Nature.
NTBG's research programs are enhanced by partnerships with research associates who utilize or curate NTBG's living and herbarium collections, engage in collaborative research projects with staff, and contribute expertise that complements the skills of existing staff members.
