FNR Introduces New Faculty and Staff Members

Nine individuals have joined the Purdue Department of Forestry and Natural Resources in faculty or staff roles since August 2021.

Dr. Peter Euclide, Laura Fehling, Theresa Hudson, Ben McCallister, Rhonda Taylor, Abby Valachovic and Stephen Volz have joined the FNR staff in the past year, while Dr. Morgan Furze and Dr. Dylan Wainwright joined the faculty in August 2022 with 25% FNR appointments. Furze has a majority appointment in the department of Botany and Plant Pathology, while Wainwright’s major appointment is in the department of Biological Sciences.


Peter Euclide

Dr. Peter Euclide joined the FNR staff in 2021 as a collaborative researcher between the department of biology and FNR under Dr. Mark Christie. Beginning in October 2022, he will begin working more extensively with Dr. Tomas Höök and Illinois-Indiana Sea Grant. Euclide uses a combination of modern genomic techniques and ecology to answer questions related to animal movement, local adaptation, and evolution to inform management and conservation. Much of his research has investigated the population ecology, genetic structure and local adaptation of fishes in the Great Lakes, including walleye, lake trout, yellow perch and alewife.

“In my short time at Purdue the FNR department has been a great and welcoming place to work and I am excited to be part of the team of scientists conducting natural resources research in the Christie and Höök laboratories,” Euclide said.

Euclide comes to Purdue after spending the past year as a postdoctoral research associate at the University of Wisconsin-Milwaukee, where he studied population genomics of fish and mammals and managed a collaborative Great Lakes wide walleye research program. Prior to that, he was a genetics research scientist for the U.S. Geological Survey’s Wisconsin Cooperative Fishery Unit. In both positions, he worked primarily on population genetics of freshwater fisheries, eDNA metabarcoding, and the development of genetic marker panels for natural resource management of walleye, lake whitefish and white-tailed deer.

Euclide completed his undergraduate degree in organismal biology at Kent State University in 2012, graduating summa cum laude. He went on to earn his master of science degree in 2015 from the Rubenstein School of Environment and Natural Resources at the University of Vermont, presenting his thesis on “Fixed versus plastic partial migration of the aquatic macroinvertebrate, Mysis diluviana, in Lake Champlain.” In 2018, Euclide earned his doctoral degree from the department of biology at Vermont, presenting his dissertation on “Genetic consequences of habitat fragmentation in the Champlain basin.”

Euclide’s research has produced more than 20 publications, including three in 2022: “Genome-wide genetic diversity may help identify fine-scale genetic structure among Lake Whitefish spawning stocks in Lake Erie” in the Journal of Great Lakes Research; “Further evidence from common garden rearing experiments of heritable traits separating lean and siscowet lake charr (Salvelinus namaycush) ecotypes” in Molecular Ecology; and “A chromosomal inversion may facilitate adaptation despite periodic gene flow in a freshwater fish” in Ecology and Evolution..

In addition to his research, Euclide acts as a manuscript reviewer for several publications, including the Journal of Great Lakes Research, the Canadian Journal of Fisheries and Aquatic Science, the North American Journal of Fisheries Management, Ecology and Evolution, PLoS1 and Molecular Ecology.

In Dr. Christie’s lab, Euclide is working a number of different projects, including a study using whole-genome sequencing to investigate the evolution of yellow perch populations in Lake Michigan. The focus of these studies is to understand the origin of yellow perch in drowned river mouth lakes and to investigate how fisheries induced evolution has influenced yellow perch populations in southern Lake Michigan. In addition, Euclide recently began a new line of research looking at the influence of hatcheries on the evolution of Pink Salmon in Alaska.

He recently received a grant from the Great Lakes Fish and Wildlife Restoration Act, which will fund research evaluating the genetic stock structure of lake whitefish in Lake Erie and evaluate the potential for existing genetic marker panels to aid with management of Lake Erie lake whitefish recreation and commercial harvest.


Laura Fehling

Laura Fehling headshotLaura Fehling joined FNR on June 1 in the role of Natural Resources Lab Coordinator and Collections Curator. Fehling comes to Purdue after completing her master of science degree in Botany at Miami University in Oxford, Ohio, in May 2022.

“I am very excited to be taking on this new position with Purdue FNR which provides a unique opportunity to work in multiple roles as a teacher, curator, and director for summer practicum,” Fehling said.

Fehling’s thesis work tested the context dependency and benefits in a multispecies mutualism working at a greenhouse, field site, and laboratory with plants, insects and microbes. She also acted as a graduate teaching assistant for three courses: Biological Concepts: Ecology, Evolution, Genetics and Diversity (BIO 115), Biological Concepts: Structure, Function, Cellular, and Molecular Biology (BIO 116) and Field Botany (BIO 155).

As an undergraduate at the University of Wisconsin-Green Bay, Fehling majored in environmental science and minored in biology. She served as a research intern at the Forest Preserves of Cook County in River Forest, Illinois, building a database on native plant species and their relevant physiological traits, habits and other factors affecting the vigor of the species. In that role, she also removed invasive species, collected seeds and maintained native plant species, while using GPS and technology to map signage in forest preserves throughout the county. Fehling also volunteered with Openlands Treekeepers in the Chicago region, earning certifications in tree identification, planting and care. She also planted, trimmed and maintained trees throughout the region, while working to educate the public on the importance of native trees and best practices to care for them.

Fehling also gained experience in plant biology and conservation as an herbarium research assistant at Gary A. Fewless Herbarium in Green Bay and as a National Science Foundation Research Experience for Undergraduates intern at the Chicago Botanic Gardens. At the herbarium, she collected plant specimens, made professional mounts and maintained storage and organization of the specimens, while cataloguing them in an online database. As an REU intern, Fehling worked on a project regarding the impact of drought on plant-herbivore interactions involving evening primrose and hawkmoth caterpillars. She also worked in a greenhouse and lab maintaining plants as well as scientific equipment and tools. As an undergraduate researcher at UW-Green Bay, Fehling designed and conducted an experiment involving the use of mealworms to consume and recycle otherwise non-biodegradable polystyrene waste.

In her role as Natural Resources Lab Coordinator, Fehling will teach Vertebrate Systematics and Ecology (FNR 242 and 252) and Dendrology (FNR 225). She also will serve as Summer Practicum director, and maintain the departmental vertebrate and herbarium/arboretum specimen collection.


Morgan Furze

Dr. Morgan Furze began her appointment as an assistant professor in Botany and Plant Pathology and Forestry and Natural Resources in August 2022.

Furze comes to Purdue after spending the last year as a U.S. Department of Agriculture National Institute of Food and Agriculture (USDA NIFA) postdoctoral fellow in the McElrone lab of the University of California, Davis Department of Viticulture and Enology. This followed a two-year stint as the Donnelley postdoctoral fellow in the Brodersen lab at the Yale University School of the Environment.

Furze earned her bachelor’s degree in biology from Bucknell University in 2012. She then completed her PhD in organismic and evolutionary biology from Harvard University in 2019. Her dissertation was on “Understanding Whole-Plant Nonstructural Carbohydrate Storage in a Changing World.”

“I’m looking forward to collaborating with everyone in the FNR community through research, teaching and extension,” Furze said.

In 2019, Furze was awarded a Rising Star in Organismal Botany Award from the Society for Integrative and Comparative Biology. She also has received Distinction in Teaching Awards from Harvard twice for her work with OEB 52 Biology of Plants (2018) and OEB 10 Foundations of Biological Diversity (2017).

Her research focuses on plant ecophysiology. Furze utilizes tools from plant physiology and ecology along with microCT imaging and machine learning technology to explore nonstructural carbohydrate storage and allocation in response to stress in ecologically and economically important plants, especially trees, to help quantify and predict plant and ecosystem responses to global change.

Furze has published 11 papers, most recently discussing “Ecologically driven selection of nonstructural carbohydrate storage in oak trees” in New Phytologist, and has two more in review. 

She is the program officer-elect for the Division of Botany with the Society for Integrative and Comparative Biology and was a representative on that organization’s student-postdoctoral affairs committee. She also is an assistant editor of Integrative and Comparative Biology and a reviews editor for Frontiers in Forests and Global Change.


Theresa Hudson

Theresa Hudson headshotTheresa Hudson began working as a research technician in Dr. Jeff Dukes’ lab in April 2022. She is the lead technician on an experiment at Martell Forest, where researchers are studying how plants’ exposure to water stress over time affects its subsequent responses to water stress, i.e. are plants able to acclimate or make physiological adjustment that allow them to cope with water stress better the more times they experience it.

“"I am excited to contribute to research that has the potential to affect our understanding of how climate change will impact the world’s ecosystem,” Hudson said. “Since starting my career in ecology and conservation way back in undergrad, I have only ever wanted to make a positive impact on the environment through my work, and this position helps me do that. I am also excited to broaden my horizons by doing work in the field of forestry and to learn several new skillsets along the way. Both of which, I am happy to say, have already begun".

Hudson earned her bachelor’s degree in environmental science from IUPUI (Indiana University Purdue University Indianapolis) in 2018. She went on to complete a master of science degree in conservation ecology and sustainable development from the University of Georgia in 2021. Her main interests include the conservation of endangered species and their habitats in the face of anthropogenic change including urbanization and global climate change.

Hudson was a lab tech assistant in the IUPUI Department of Earth Sciences as an undergraduate student, working on projects funded by the Undergraduate Research Opportunity Program. She investigated the origin and characteristics of trilobite fossils through the use of a microscope, Adobe Photoshop and library research as well as collaboration with museums and universities. She also identified algae found in the Antarctic tundra by collaborating with labs and researchers to attain DNA information, radio carbon age and electron microscope images.

As an undergraduate research intern at the Gobabeb Research and Training Center in the Namib Desert in Namibia, Hudson collected plant and soil samples during fog and dew events and measured plant and soil water potential to determine stable isotope composition and reliance of desert plants on fog and dew as a water resource.

As a graduate researcher at the El Verde Field Station in the El Yunque National Forest in Puerto Rico, she planned, set up and conducted a six-week field experiment in a montane headwater stream investigating the top-down effect of shrimp on algae.

As a volunteer with the Environmental Law Practicum in Athens, Georgia, Hudson researched the conservation status and ecology of sea turtle species in the water surrounding the United States to determine improved conservation strategies and required protections for different species based on the individual and varying severity of the threats they faced. Along with an interdisciplinary team of graduate students, she then drafted that research into a federal legislative proposal for the Georgia Department of Natural Resources.

In addition to her research, Hudson worked as a lab instructor for an undergraduate ecology lab course covering endangered species, ecological succession, food webs, evolution and disease ecology, as well as field techniques ranging from taking soil cores, measuring soil moisture and pH, sampling and identifying macroinvertebrates, to sampling plants and identifying tree species. Most recently, she worked as a lab technician for the Center for Applied Isotope Studies at the University of Georgia. In that position, she prepared and analyzed soil, algae, plant/animal tissue, bone and mineral samples for carbon and nitrogen isotopes.

Hudson’s research in the Dukes Lab is based in a 25-year old forest stand at Martell Forest, as well as a couple other locations at Martell. Elin Jacobs is leading the modeling portion of the project, while the research also includes collaborators at Indiana University, Los Alamos National Laboratory and Pacific Northwest National Laboratory (PNNL).
