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.

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

Wendy Clement

Wendy Clement

Associate Professor, The College of New Jersey
Jewett Prize and Visiting Scholar, Arnold Arboretum of Harvard University

Wendy will study floral traits using the living collections of Lonicera (honeysuckles) at the Arnold Arboretum. She is interested in using trait data, such as color, morphology, rewards, and floral scent to describe the evolutionary history of floral form in Lonicera and identify potential instances of shifts in pollination syndrome.

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, Arnold Arboretum of 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.

Steve Gougherty

Steve Gougherty

PhD Student, Boston University
Deland Award Recipient and Visiting Fellow, Arnold Arboretum of Harvard University

Steve is developing a new framework to consider nutrient use efficiency (NUE) in plants beyond the traditional methods focused on vegetative tissues. As a Deland Award recipient, he will measure the carbon and nitrogen costs of reproduction in samaras, a type of fruit. Samaras are green during seed development, suggesting active photosynthesis, but tend to lose their pigments as seeds mature.

Caio Guilherme Pereira

Caio Guilherme Pereira

Postdoctoral Associate, Massachusetts Institute of Technology (MIT)
Visiting Fellow, Arnold Arboretum of Harvard University

Caio Guilherme Pereira aims to understand the molecular mechanisms of plant-environment interaction and discover how this interaction plays a role in the underlying growth pattern, composition and diversity of the plants.

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.

Julia Marrs

Julia Marrs

PhD Candidate, Boston University
Visiting Fellow, Arnold Arboretum of Harvard University

Julia Marrs interests include terrestrial carbon cycling and remote sensing of vegetation. Currently she is investigating the link between the solar-induced chlorophyll fluorescence signal measured by tower and satellite platforms and plant physiological processes occurring at the leaf level.

Natalia Pabon Mora

Natalia Pabón-Mora

Associate Professor, University of Antioquia in Colombia
Jewett Prize Recipient and Visiting Scholar, Arnold Arboretum of Harvard University

Natalia Pabón-Mora is interested in understanding the evolution of flower and fruit development and the morphological changes driving diversification of flowering plants. As a Jewett Prize recipient, she will focus on fruit diversity by comparing morphological and anatomical features and transcriptomic data of members of the Rubiaceae with distinct fruit types.

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.

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.

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.
