Profile

I am from Santa Fe, NM. I received a Bachelor of Science (2017) from Humboldt State University in Arcata CA, where I double majored in Botany and Biology with an emphasis on ecology and biodiversity. In the redwood forests of northern California, I became captivated by the ferns and other non-flowering plants. My undergraduate research focused on tissue culture, fern gametophyte morphology (using scanning electron microscopy), and chromosome staining in a hybrid complex of the genus Polypodium. In my free time, I enjoy cooking Japanese food, visiting museums, and staying active through hiking and yoga.

Research Description

My research interests have been greatly influenced by the life and work of the famous 18th century naturalist Alexander von Humboldt. Like Humboldt, I seek to maintain a holistic approach to my research by unifying diverse branches of scientific disciplines, such as systematics, ecology, and evolutionary biology.  In 2019, I joined the Barrington-Sundue Lab as a PhD student to uncover and characterize diversity, taxonomy and distribution of extant fern lineages. Currently, my research is focused on a model-based approach to explain patterns of fern diversity, in addition to a reexamination of Athyrium (Athyriaceae) systematics in temperate North America and the neotropics.

Aayudh Das

Profile

Grown up in the city of joy of India i.e. Kolkata (formerly Calcutta), I completed my Bachelor’s in Botany from Presidency College, Kolkata. In the beginning of 2014, I got the opportunity to work as a Research Assistant in South Dakota State University where I worked on identifying of heat and drought stress-responsive proteins in soybean seedling proteome and also involved in pre-harvest sprouting of wheat in a metabolomic approach. Alongside, I also investigated the proteomic responses of switchgrass and prairie cordgrass to senescence. In the end of 2014, I joined Texas A&M University, College Station where I followed through my previous research and completed my Master’s in Biochemistry (2016). In addition to research, I enjoy playing acoustic guitar, singing and cooking Indian food.

Research Description

In early 2016, I joined Plant Biology graduate program as a PhD candidate and started working under Dr. Jill Preston where I worked on genomic comparison of freezing and drought stress responses across the temperate cereal grass clade Pooideae. Currently, I’m examining the physiological and genetic intersections between drought and freezing tolerance in Pooideae.

Profile

I was born in Rock Springs, Wyoming. I moved to Vermont when I was seven and have lived here since. I received my B.S. in Plant Biology from the University of Vermont in 2013. I did undergraduate research in the Barrington Lab working on the reproductive biology of Vermont’s Polypodium species. I enjoy skiing, playing guitar, and playing soccer.

Research Description

Plant development is unique from animals in that living cells are fixed in place and enclosed within a cell wall matrix. As an apical meristem grows divisions are made adding cells to the top of the plant body. In this sense plant development is a process of construction, and the addition of new cells is in part governed by the physical arrangement of existing ones. Assessing how mechanical inputs influence processes of cell division and differentiation is a goal of this project. In doing this we aim to create a system in which mechanical forces can be applied to isolated plant cells in a consistent manner.

I hail from “the God’s own country,” Kerala, a small southern state in India. Forest fragmentation and it’s ecological consequences have always intrigued me and thus steered me towards this stream of research. I am interested in studying the effects of climate change on the local adaptability and gene flow of forest tree species, as well as landscape genetics and spatial analysis. Prior to joining the Keller lab in 2018, I completed my B.Sc. (Hons.) and M.Sc. in Forestry with specialization in Tree Physiology and Breeding at Kerala Agricultural University. During that time, I investigated the effects of particulate pollution on the growth and physiology of trees in moist deciduous forests. In addition to research, I love to read, illustrate and play games.

Morgan Southgate

Profile

I grew up just outside of Montpelier, VT, and spent most of my time when not in school exploring the forests both around my house and the larger areas of wilderness in the Green Mountains. After graduating high school, I traveled across the US for half a year visiting different national parks and wilderness preserves. I was set to begin at UVM the following fall in the Environmental Science program, but realized during my travels that I wanted to focus my education around plants specifically. I began my Plant Biology major at UVM in 2013, and was quickly drawn in by the detailed education I received about plants from systematic, evolutionary, physiological, and ecological perspectives, as it provided the perfect complement to my pre-existing personal relationship with plants developed from a lifetime spent in the woods. During my undergraduate career, I worked at the Pringle Herbarium and the Proctor Maple Research Center, and joined the Barrington Fern Systematics lab. I focused my undergraduate research on the ecology and biogeography of the Adiantum pedatum complex, a clade of maidenhair ferns here in VT. This research captivated me so thoroughly that I decided to continue this research as a graduate student here at UVM.

Research Description

I am a MS student in the Barrington Lab, and my primary interest is plant ecology. My current research on the ecology of the Adiantum pedatum complex focuses on characterizing the ecological niche of the three species which comprise the clade, including two diploid progenitors and their tetraploid hybrid, and on understanding how the hybrid ancestry of the tetraploid hybrid A. viridimontanum is reflected in its ecological preferences. In the future, I intend to continue learning about why plants grow where they do, and especially about the importance of substrate in shaping plant distribution. Ultimately, I plan to apply this knowledge towards wilderness conservation and ecosystem remediation.

I graduated in 2016 from Skidmore College, where I majored in Biology and minored in Mathematics. During my time at Skidmore, I worked in Dr. David Domozych’s lab for all my 4 years, where I was introduced to plants. While there, I worked with the unicellular green alga Penium margaritaceum. We worked on Penium margaritaceum’s cell wall and developing it as a single cell plant model system. In my free time, I like working out, watching sports, and coaching for the UVM Crew Team.

Research Description

Currently, I am working on the functional evolution and the biochemical characterization of the MtLATD/NIP gene which encodes for a nitrate transporter in the model legume Medicago truncatula. This gene is required for root and nodule development and is expressed in the respective meristems. The LATD/NIP gene originated at the base of angiosperms, but it is not clear when it acquired the meristem function. To test this, I am checking the ability of the orthologs to rescue the latd mutant phenotype.

Brittany Verrico

Profile

I am from Pittsburgh, Pennsylvania where I received a B.A. in Biology and German from Washington & Jefferson College. My interest in plants began in high school while making a plant scrapbook that creatively explained the life cycle of a tree and I have since followed my intellectual curiosity of plants. My undergraduate research focused on plant ecology and vegetative phenology. As an intern in Dr. John Parker’s lab at the Smithsonian Environmental Research Center (SERC), I investigated how phenotype, phylogenetic similarity, and introduced status influences community assembly. I enjoy hiking, photography, reading, cooking, and crafting.

Research Description

My academic interests lie at the confluence of population genetics, ecology, climate change, and forest tree biology. As a graduate student in the Keller Lab, I seek to understand how gene flow and selection structure genetic diversity and adaptation across fine-scale environmental and climatic gradients. I am using the boreal tree red spruce (Picea rubens) as a focal species, which is a dominant component of high elevation northeastern forests. I am also using a 50-year chronosequence to analyze forest community change and the upslope shift of the boreal-deciduous forest ecotone in the Green Mountains, VT.
