Sargent Award Recipients

Our Sargent Award Recipients

Made possible by the generosity of Dr. Jack Wittenberg through the Charles Sprague Sargent Fund, the Sargent Award provides support for visiting scholars in the botanical sciences to conduct basic research that utilizes the living, library, and/or herbarium collections of the Arnold Arboretum.

 

Kathryn Mauz

Kathryn Mauz

2019 Sargent Award
Independent Scholar

The Jesup Collection of North American Woods, a collection of nineteenth-century log specimens, was the product of a collaboration between the Arnold Arboretum during Charles Sargent’s tenure and the American Museum of Natural History. Kathryn will document the geographic origins of these specimens using archival and herbarium resources related to the original project. With robust documentation, the specimens could contribute meaningfully to scientific research, for example, by analyses of tree rings to address climate history.

Margaret Grose

Margaret Grose

2018 Sargent Award
Senior Lecturer, University of Melbourne, Australia

Margaret will focus on EH Wilson’s collecting trip to Australia in 1920-21. Unlike Wilson’s trips to China, much less is known about this trip. Margaret will dive into the Arboretum library archives to examine Wilson’s field notes, letters, and images documenting Wilson’s time in Australia.

Dong Wang

Dong Wang

2018 Sargent Award
Assistant Professor, University of Massachusetts, Amherst

Dong is 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 will examine the rhizobia present in root nodules at the Arboretum.

Scott Dietrich at Wilson's stump in Japan

Michael and Scott Dietrich

2017 Sargent Award
Professor, Dartmouth College (MD)
Co-Curator, Hong Kong Stair Archive (SD)

Michael and Scott Dietrich are brothers with a common passion for EH Wilson. Pulling from the over 7000 images in the Arboretum library archives, they will search for the perfect images for their upcoming book, The Photography of Ernest Henry Wilson.

David Basler

David Basler

2017 Sargent Award
Postdoctoral Fellow, Harvard University, Richardson Lab

David Basler is a postdoctoral fellow at Harvard University. In a close collaboration with Margaret Kosmala (Sinnott Award), high-resolution multispectral photographs and localized temperatures of the Arboretum over time will be gathered using an unmanned aerial vehicle (drone) and temperature loggers. With this data, they will examine the relationship between plant phenology (the timing of life events) and genetic adaptation in response to local topography and temperature.

Kuo-Fang Chung

Kuo-Fang Chung

2016 Sargent Award
Associate Research Fellow, Biodiversity Research Center, Academia Sinica, Taiwan

Kuo-Fang Chung will explore the rich herbarium and living collections of Berberis to clarify the taxonomy of the genus.

Dan Sullivan

Dan Sullivan

2016 Sargent Award
Visiting Fellow of the Arnold Arboretum

Dan is developing techniques for rapid and inexpensive DNA extraction as well as cultivating collections of extracted DNA libraries and silica-dried leaves for future phylogenetic research.

Jianhua Li

Jianhua Li

2015 Sargent Award
Associate Professor of Biology, Hope College

A former Arnold Arboretum senior scientist, Jianhua will return to the Arboretum for his sabbatical focusing 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.

Luke Keogh

Luke Keogh

2015 Sargent Award
Post-doctoral Fellow, Ludwig-Maximilians University, Germany

Luke’s research focuses on the role of Wardian Cases, an early 19th century invention, in the movement of live plants between continents. Using the Arboretum’s archival collections, he will delve into the role of the United States in this global transfer of plants.

Andrew_03-05-14sq

Andrew Groover

2014 Sargent Award
Geneticist, USDA Forest Service

Andrew 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.

RosanneHealyTrufflingFSP2009

Rosanne Healy

2013 Sargent Award
Post-doctoral Fellow, University of Minnesota

Rosanne focuses 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. Matching funds for this award was generously provided by the Harvard Forest.

HughMcAllister

Hugh McAllister

2012 Sargent Award
Honorary Lecturer, University of Liverpool

Hugh is interested in examining the evolutionary relationships of species within genera. By comparing chromosome numbers, he seeks to clarify the relationships between diploid and polyploid species. Previous visits to the Arnold Arboretum and the Harvard University Herbaria led to the publication of monographs on genera Betula and Sorbus.

Claire Williams

Claire Williams

2012 Sargent Award
Distinguished Scholar, Forest History Society

Using the Arboretum’s conifer collection, Dr. Williams will determine whether pollen dispersed during the day or at night is more highly represented within the micropyle of female cones.
