Our Visiting and Associated Scientists

Renaud Bastien A post-doctoral fellow in the Mahadevan Lab, Harvard School of Engineering and Applied Sciences, Renaud Bastien is interested in the dynamics and regulation of plant growth and development. His work currently focuses on the formation and development of thorns, specifically in holly.
Boufford Dave Boufford, senior research scientist at the HUH, has been leading exhibitions to Asia since 1977. Along with several colleagues, he is undertaking a survey of the plant and fungal diversity of the Hengduan Mountain region in southwestern China, one of the world’s hotspots of biodiversity. His expeditions in unexplored and underexplored regions complement collections made in the first half of the twentieth century by Joseph Rock, TT Yü, C. W. Wang, R. C. Ching, and others.
Anthony R. Brach, editor at the Missouri Botanical Garden and research associate for the Harvard University Herbaria, has a strong interest in the plants of Asia including their taxonomy, identification, and ecology. An editor of the Flora of China Project, he is interested in exploring the digitization and creation of web-based floras and interactive identification keys.
Andrew_03-05-14sq A geneticist at the USDA Forest Service and a Sargent Award recipient, Andrew Groover will perform RNA sequencing (RNA-seq) on cambium and wood forming tissues of diverse trees in the Arboretum. Potentially important regulatory genes expressed in these tissues will be identified and analyzed as a first step to understanding the evolution of woody growth.
Ling Guo is a curator at the Beijing Botanic Garden and a Jewett Prize recipient. Utilizing the Arboretum’s Malus collection, she will conduct research to improve the databases and knowledge of ornamental crabapples as a Registration Authority. Her database will focus on the flowers of Malus to improve the understanding of flowering time.
RosanneHealyTrufflingFSP2009 Rosanne Healy, Sargent Award recipient and post-doctoral fellow at the University of Minnesota, is focusing on ectomycorrhizal fungi that are present on roots of trees in well-spaced habitats like the Arboretum. She plans to sequence, identify and compare the fungal partners on the roots of Oak trees present at the Arboretum with those at the Harvest Forest.
Abby Hird Conservation of threatened plant species is of great interest to Abby Hird. As a scientist for Botanic Gardens Conservation International–United States (BGCI-US), she collaborates with the Arnold Arboretum to implement the recommendations of the North American Collections Assessment. The goal is to preserve threatened taxa and increase genetic diversity by growing threatened plants in the living collection of the Arboretum and other botanical gardens.
Ursula_King Ursula King is a PhD student at the University of Connecticut, interested in the evolution of aquatic plants. Specifically, she is developing molecular markers to explore the population dynamics and reproductive biology of Najas flexilis (Hydrocharitaceae), a monoecious, freshwater annual, in which pollination is entirely underwater. As a visiting fellow in the Friedman Lab, Ursula is learning techniques to observe ovule development in this species.
Michael Long is a Sargent Award recipient and post-doctoral researcher in the Musah Lab at the University at Albany. His research will focus on a new non-destructive technique (direct analysis in real time mass spectrometry or DART-MS) to generate “chemical fingerprints” of material from the living collection and herbarium including wood and flowers. Generation of these profiles will increase our understanding of the chemical diversity present in the Arboretum.
KristelPicture Kristel Schoonderwoerd is a Deland Award recipient, visiting from the Erasmus Mundus Master Program in Evolutionary Biology. Interested in many facets of evolutionary botany, Kristel has previously worked on comparative evo-devo of stomates and chloroplast protein import. At the Arboretum, she is studying reproductive traits in angiosperms on a macroevolutionary scale and examining reproductive development of Franklinia alatamaha.
Harvard Forest E. C. Jeffrey Professor of Biology, Emeritus Barry Tomlinson has done extensive research on developmental morphology of pollen and cones in conifers. He is currently collaborating with the Arboretum to investigate the composition and role of pollination drops in conifers.
