Graduate Students

Fern Bromley

PhD Student
Fern is a graduate student studying Natural Resources with an emphasis in Watershed Management and Ecohydrology. With a background in field botany, plant ecophysiology, and the carbon & water cycles, Fern is broadly interested in how different functions of plants and the ecosystems they make up respond to changing water availability and hydroclimate. Fern decided to pursue a grad degree after working in the conservation industry in Arizona for several years and becoming interested in reciprocal knowledge exchange between scientists and land managers. They are currently working on two main projects: one concerning the effects of vegetation management on groundwater recharge, including groundwater dependency of certain plant communities; and another assessing conifer seedling vulnerability to extreme heat and drought using physiological indicators, particularly to inform how seedling mortality might affect ecological trajectories and reforestation planning in the US’s intermountain region.

Cameron Crowder

Springfield Fellow, Masters student

Cameron was born in Cypress, Texas, and went to St. Edward’s University for a BS in Environmental Science and Policy. During her time there, she had various internships and conducted summer research with the McNair Program on soil amendments and their effects on switchgrass. Those experiences led her to pursue an MS in Natural Resources. Her research interests include methods for improving ecosystem resilience and the impact of changing climates on native and invasive species

Ethan Taber

PhD Student
NSF Graduate Research Fellow
JFSP GRIN Fellow

Ethan grew up in rural Oklahoma, but moved west and earned a BA in Environment and Sustainability at Western Colorado University. After a few years working in the northern Rockies, the desire to further his education led him to NAU. Ethan’s main research interests involve plant community responses to the effects of a changing climate, specifically involving wild land fire and reduced snowpack.

Madeleine (Maddie) Wallace

PhD Student
Carson Scholar

Maddie received her BS in Environmental Sciences from the University of Portland in 2020. After graduation, she spent a few years doing ecological restoration in the Willamette Valley ecoregion, working in grassland, oaks woodland, riverine, and wetland habitats. Her passion for restoration and desire to learn more about how land management decisions are made inspired her to pursue an MS in Natural Resources at the University of Arizona.  Maddie’s research interests involve plant community response to climatic changes, specifically drought response and resilience in restoration species.

Ian Winick

PhD Student

Ian was born in a tide pool on the shores of Long Island Sound. He earned his BS in Biology at Queen’s University and his MPS in Natural Resources and the Environment at Cornell University. Ian is broadly interested in native plant conservation from the species scale to the landscape scale. His master’s work was on the restoration ecology of a rare perennial herb in the Finger Lakes region of New York. His current research is focused on the resilience of plant communities in the context of changing climate and disturbance regimes, with the goal of informing thoughtful, research-driven land stewardship.

Elwin Jay “EJ” Salac

Lab Logo Designer

Northern Arizona University B.S. Environmental Sciences

Our Logo was designed by Elwin Jay “EJ” Salac. Elwin Jay “EJ” Salac is an alumnus of Northern Arizona University’s Environmental Sciences program and has also spent a bit of time doing freelance graphic art. Born and raised in the Sonoran Desert surrounded by the natural scenery and exposed to a whole lot of Bob Ross, the environment and nature continues to be a big portion of their work in both the areas of graphic design and painting. EJ takes graphic art commissions, and can be reached at elwin.jay.salac (at) gmail.com.

Undergraduate Students

Annika Gooding

Undergraduate Researcher
UA Undergraduate Biology Research Program

Annika is from Tucson, Arizona and is currently an undergraduate student majoring in Natural Resources with an emphasis in Wildlife Conservation and Management. She has an interest in how arid ecosystems are being impacted by human disturbance. Her current research centers invasive species management, with a focus on reducing the seedbank of Oncosiphon pilulifer (stinknet) to support native plant communities

Doan Goolsby

Undergraduate Researcher

Doan is an Arizona native, and is currently pursuing an undergraduate degree in the School of Natural Resources and the Environment, focusing on Ecology, Restoration, and Management of Rangelands, complemented by a certification in Geographic Information Systems (GIS). His research is dedicated to invasion ecology, with a specific interest in the spread of Oncosiphon piluliferum (Stinknet) in Pima County. He seeks to explore the ecological niche alterations of Stinknet from its native range of South Africa, and is in the process of creating a management tool to assist land managers in their efforts to control this invasive species.
