I’m interested in using knowledge of plant phylogeny to understand morphological character evolution, diversification, and historical biogeography. Several current projects are focused on elucidating the evolution of Viburnum and its movements among continents and forest communities.

Ian Gilman

I am interested in trait evolution and the resulting patterns of diversification. In particular I am working on the evolution of organ fusion in the Honeysuckles (Lonicera) and how this trait has affected diversification. I am also studying the evolution of CAM photosynthesis in the Portulacinae in collaboration with the Edwards Lab at Yale. While these traits are complex, requiring biochemical and morphological modifications, they have evolved multiple times within flowering plants. Tracing these traits’ histories through space and time may reveal patterns common to many lineages of plants. I am also interested in phylogenetic methods, specifically the problems faced by phylogenetics in the genomics age. I received my M.S. in Biological Sciences from the University of Idaho in 2017, where I studied systematics of a rare genus of salt-marsh endemic plants, Chloropyron, in the Tank Lab.

I am fascinated with the amazing diversity of floral displays across the angiosperms. To this end, I employ an integrative approach spanning developmental genetics, pollination ecology, and phylogenetic biology to gain insights on the proximate and ultimate factors that generate this diversity.

For the last 5 years, I have been conducting experiments in western Massachusetts to study the pollination ecology of the hobblebush, Viburnum lantanoides. Like sunflowers and hydrangeas, hobblebush produce showy inflorescences composed of a central cluster of small, fertile flowers encircled by large, sterile flowers, that as a whole, make the inflorescence look and function like a single flower. Its not clear why hobblebush (or sunflowers and hydrangeas for that matter) do this, so I have been collecting data on insect visitation and fruit set in a population of hobblebush composed of “wild-type” plants with sterile flowers and experimental plants with their sterile flowers removed. I hope results provide insights into the role of natural selection in driving the evolution of sterile flowers in hobblebush.

This work has been a truly collaborative effort, with involvement from several undergraduate students, PhD students, and postdocs. If you are interested in getting out into the field, please contact me by email.

Miranda Sinnott-Armstrong

I am a fifth-year graduate student interested in seed dispersal and how plants entice animals to consume their fruits.  I am currently working on describing spatial patterns in fruit colors, as well as investigating underlying evolutionary mechanisms behind these patterns. Broadly, I am interested in biogeography and trait evolution.

Current Lab Associates
Patrick Sweeney
Collections Manager, Yale University Herbarium, Peabody Museum of Natural History

My interests are far ranging and include flowering plant systematics and evolution, North American floristics, and biodiversity informatics.  My more recent systematic research focuses on Viburnum (Adoxaceae) and the mangosteens (the genus Garcinia, Clusiaceae). I am interested in the North American flora and I have conducted survey and inventory work in the eastern and central United States. I am also heavily involved in several herbarium digitization projects, including the New England Vascular Plants and Lichen/Bryophyte TCNs, among others.

Current Postdocs
Michael Landis
NSF Postdoctoral Research Fellow, Ecology and Evolutionary Biology

My current research aims to better understand when, why, and how groups of species came to live where they’re found today, particularly over deep timescales, and to reconcile the behavior of probabilistic models of evolution with empirical data and evolutionary theory. My broader interests include in evolutionary biology, phylogenetics, biogeography, and quantitative trait evolution, in addition to probabilistic models, Bayesian inference, and bioinformatics.

I am interested in why some clades of organisms contain more species than others, and within this context, I’m particularly interested in the long recognized relationship among flowering plants where families with more specialized pollination mechanisms tend to have more species. To understand this pattern I study how flower evolution affects rates of speciation, and reciprocally, how interactions among co-occurring species, especially within highly diverse clades, affects flower evolution.

I am interested in the ecology and evolution of mutualisms. Among other things I study mechanisms that promote cooperation and prevent cheating in the mutualism between fig trees and their pollinating wasps.

I am interested in the relationships between form, function, and morphological evolution. My work focuses on seed plant reproductive structures and integrates data from the paleontological record, experiments in living analogues, and phylogenetic analyses in order to understand how the various functions that reproductive structures perform have driven patterns of morphological change.  In addition, my work also includes several field-based paleobotany projects focusing on fossil floras from eastern North America, New Caledonia, and Mongolia.

I’m broadly interested in the evolution of plant morphology and function, especially in climatically extreme environments. I take a whole-plant perspective, applying data from ecophysiology, morphology, and niche-modelling approaches to try to understand how evolutionary change is integrated at the level of the organism. I’m particularly interested in the question of why some plant lineages show extensive morphological and ecological lability, while others seem to stick with the tried-and-true. My current project looks at trait evolution and community assembly in high-altitude environments of the Andes mountains.
