Visiting Scientists

Our Visiting and Associated Scientists

In addition to our staff scientists, the Arnold Arboretum shares its resources, the state-of-the-art research facilitiesliving collection, herbarium, plant records, library and archives, with scholars at Harvard and around the world. Formally-affiliated scientists are introduced below, but we open up our resources to an extensive network of researchers for a diverse range of research projects and offer fellowships, awards and internships. Learn more about requesting research access to the Arboretum living collections, research facilities, or library.

Boufford

Dave Boufford

Senior Research Scientist, Harvard University Herbaria
Associate, Arnold Arboretum of Harvard University

Dave Boufford 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 Brach

Research Associate, Harvard University Herbaria
Associate, Arnold Arboretum of Harvard University

Anthony R. Brach has a strong interest in the plants of Asia including their taxonomy, identification, and ecology. As an editor Missouri Botanical Garden and of the Flora of China Project, he is interested in exploring the digitization and creation of web-based floras and interactive identification keys

David Des Marais

David Des Marais

Assistant Professor, MIT
Associate, Arnold Arboretum of Harvard University

The research of David Des Marais focuses on how plants interact with the environment and the variation in these interactions between species. Understanding how plants adapt to the local environment can increase our ability to conserve plant populations.

Ailene Ettinger

Ailene Ettinger

NSF Fellow and 2014 Putnam Fellow
Visiting Fellow, OEB, Harvard University

Ailene Ettinger, Arnold Arboretum Putnam Fellow and NSF Fellow, focuses on predicting the response and sensitivity of plants to a changing climate. By examining diverse trees growing in a common environment like the Arboretum, she can identify functional traits that are important for success outside their historical conditions.

Lorna-Gibson

Lorna Gibson

Professor, MIT
Associate, Arnold Arboretum of Harvard University

The research of Lorna Gibson is focused on the mechanics of materials with a cellular structure such as engineering honeycombs and foams, natural materials such as wood, leaves and bamboo and medical materials such as trabecular bone and tissue engineering scaffolds.

Hutyra

Lucy Hutyra

Associate Professor, Boston University
Associate, Arnold Arboretum of Harvard University

Lucy Hutyra focuses on understanding the carbon cycle in an urban environment with research sites across Boston including the Arnold Arboretum. Lucy and Pam Templer collaborate with the Arnold Arboretum to set-up, operate, and analyze the data gathered from the Arboretum’s National Atmospheric Deposition Program Site (NADP site) at Weld Hill.

Jianhua Li

Jianhua Li

Associate Professor, Hope College
Associate, Arnold Arboretum of Harvard University

Jianhua Li is a former Arnold Arboretum senior scientist and a Sargent Award Recipient. Jianhua focuses on the reconstruction of the early tree of life of Acer. The evolutionary relationships of this important and diverse tree genus has, thus far, remained largely unresolved hindering our understanding of the natural history of maples.

Barry Logan

Barry Logan

Professor and Associate Dean, Bowdoin College
Visiting Scholar, Arnold Arboretum of Harvard University

Barry Logan is collaborating with Dave Des Marais, to examine divergent host spruce responses to parasitic dwarf mistletoe infection in the Arboretum.

Marjorie Lundgren

Marjorie Lundgren

Postdoctoral Fellow, MIT
Visiting Fellow, Arnold Arboretum of Harvard University

Marjorie Lundgren is a plant ecophysiologist, currently focusing on deconstructing the components of perenniality with an aim to inform crop improvement strategy.

Becky Povilus

Rebecca Povilus

Postdoctoral Fellow, MIT
Visiting Fellow, Arnold Arboretum of Harvard University

Rebecca Povilus is interested in the idea that molecular resources are important tools for connecting how changes at the gene and genome level affect developmental processes. She focuses on how evolutionary changes during the development of the egg-producing structure could give rise to the wide array of egg-sac morphologies in angiosperms.

Meri Bond - Magnolia

Adam Roddy

Postdoctoral Fellow, Yale University
Jewett Prize Recipient and Visiting Fellow, Arnold Arboretum of Harvard University

The research of Adam Roddy focuses on the physiological aspects of the evolution of flowering plants. As a Jewett Prize recipient, he is examining 25 species of basal angiosperms in the Arboretum’s living collections, Adam will measure physiological traits associated with water balance to examine the trade-offs between water transport, water storage, and the ability to maintain turgid and showy flowers.

Harold Suarez-Baron

Harold Suarez-Baron

PhD Candidate, University of Antioquia, Colombia
Deland Award Recipient and Visiting Fellow, Arnold Arboretum of Harvard University

Harold Suarez Baron is a Deland Award recipient studying Aristolochia (dutchman’s pipe) in the Arboretum’s collections. In Aristolochia, the trichomes (hairs) found on flowers are important for attracting and retaining flies for pollination. Harold focuses on the genetic mechanisms underlying trichome development in this non-model plant.

Dan Sullivan

Dan Sullivan

Sargent Award Recipient
Associate, Arnold Arboretum of Harvard University

As a Sargent Award recipient, Dan Sullivan is developing cheap and efficient techniques for extracting DNA from newly emerging leaves or silica dried leaves followed by PCR and sequencing. He is also spearheading the Dried Leaf Collection of newly emerging silica dried leaves from the Arboretum collections that are available to scholars.

Pam Templer

Professor, Boston University
Associate, Arnold Arboretum of Harvard University

The work of Pamela Templer involves examining the effects of climate change and urbanization on forest ecosystems including numerous sites at the Arboretum. In addition, Pam and Lucy Hutyra collaborate with the Arnold Arboretum to set-up, operate, and analyze the data gathered from the Arboretum’s National Atmospheric Deposition Program Site (NADP site) at Weld Hill.

Dong Wang

Dong Wang

Assistant Professor, University of Massachusetts, Amherst
Sargent Award Recipient and Visiting Scholar, Arnold Arboretum of Harvard University

Dong Wang is a Sargent Award recipient interested in the strategies that long-lived woody legumes use to interact with rhizobia, the nitrogen-fixing bacteria the live in nodules on the roots. He is examining the rhizobia present in root nodules at the Arboretum.

Wolkovich

Elizabeth Wolkovich

Associate Professor, University of British Columbia, Canada
Visiting Scholar, OEB, Harvard University

Elizabeth Wolkovich is interested in how communities assemble and disassemble in light of global changes. The Wolkovich Lab focuses on testing and understanding underlying mechanisms using both theoretical techniques and field experiments to study how current and future plant communities are shaped.

Jie Yun

Jie Yun

PhD Student, MIT
Visiting Fellow, Arnold Arboretum of Harvard University

As environmental engineer with interests in plant biology, Jie Yun is focused on solving practical environmental problems through the interdisciplinary research. She is investigating plant and environment interactions in the Des Marais Lab.

Kasia Zieminska

Kasia Zieminska

2016 Putnam Fellow
Visiting Fellow, Arnold Arboretum of Harvard University

Kasia Zieminska, Arnold Arboretum Putnam Fellow, is interested in the role of anatomy on physiological function. Kasia focuses on the role of two wood tissues, fibers and parenchyma, in tree water storage.
