Utilizing the conifer collection, Guangyou Hao, Arnold Arboretum Putnam Fellow, studied the differences in the structural, physiological, and mechanical properties of water transport and xylem hydraulics between evergreen and deciduous conifers (which shed their leaves). Guangyou is now a Research Professor at the Institute of Applied Ecology at the Chinese Academy of Sciences.
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 learned techniques to observe ovule development in this species.
The research interests of Cary Pirone, Arnold Arboretum Putnam Fellow, lay primarily in understanding how chemical signals mediate biological phenomena. Currently, she is exploring the complexities of pollination drops (ovular secretions) of several conifer species and ginkgo using biochemical and anatomical approaches.

2013

Sarah Mathews was a Sargent Fellow and principal investigator at the Arnold Arboretum. She is interested in plant phylogenetics and in the question of how changes in light-sensing systems have influenced the ability of plants to survive and diversify. The Mathews Lab uses phylogenetic, genetic, and comparative physiological approaches to explore the links between molecular and functional evolution in the phytochrome photoreceptor family.
A PhD Candidate at the University of Melbourne in Australia, Stephanie Conway is interested in the role of the shoot apical meristem in the evolution of shoot architecture. As a visiting fellow in the Friedman Lab, she focused on shoot apical meristems utilizing the extensive collection of gymnosperms at the Arboretum.
Julien Bachelier Julien Bachelier was a post-doctoral fellow in the Friedman Lab. His work focuses on the evolution of seed plants, particularly in the origin of flowering plants and the evolutionary development of flower and carpel. Julien’s thesis investigations compared the structure and development of flowers in closely related families such the Anacardiaceae and the Burseraceae.
A visiting scholar in the Friedman Lab, Biao Jin, Associate Professor at Yangzhou University, is interested in exploring the evolution of reproductive biology from gymosperms to angiosperms.
Jorge Lora is a Jewett Prize Recipient and a post-doctoral fellow with Professors Iñaki Hormaza and Maria Herrero at Experimental Research Stations – CSIC, Spain. Using members of the Arboretum’s Rosaceae collection, he compared ovule morphology from the earliest stages to maturity as well as the expression pattern of a gene thought to be important in ovule development.
Francesca Secchi The research of Francesca Secchi, a postdoctoral researcher in the Zwieniecki Lab, aims at understanding the principles of the biological function of vascular systems in plants. Her current research is focused on embolism formation and refilling using molecular, physiological, and biophysical approaches.
durio Arnold Arboretum Sargent Fellow Maciej Zwieniecki addresses the structure, surface chemistry, and mechanical properties of the network of fluid conduits in plants. The Zwieniecki Lab studies the specialized cells that distribute water, solutes, and energy over long distances, as well as how the terminal exchange surfaces (roots and leaves) interface with the environment.
Stuart Davies Stuart Davies is the director of the Center for Tropical Forest Science at the Smithsonian Tropical Research Institute. He is interested in the ecology and evolution of tropical rainforests. Using a global network of large-scale long-term forest monitoring plots, he is investigating how environmental variation and change affect the diversity and dynamics of forests.

2012

Noeline Morrissey The research of Noeline Morrissey, a master’s student in the Friedman Lab, focused on trichome morphology and development. Comparing the multiple forms of trichomes in hops (Humulus lupulus) and related genera should shed light on the evolution of these highly specialized structures.
Erica Fadon is a PhD student in the Herrero Lab at the Pomology Department of the Aula Dei Experimental Station–CSIC, Spain. Using the Arboretum’s living collection, Erica closely examined the development of sweet cherry flowers (Prunus avium) in order to determine which stage the flowers undergo winter dormancy.
HughMcAllister Hugh McAllister, honorary lecturer at the University of Liverpool, 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. Visits to the Arnold Arboretum and the Harvard University Herbaria have led to the publication of monographs on genera Betula and Sorbus.
Elizabeth Ryan is an undergraduate student at Brown University working with Dov Sax. As an Arboretum Visiting Fellow, she worked with Michael Dosmann to research plant distributions in the face of climate change. pdf »
