Jen Fraterrigo, Associate Professor

My work is motivated by a desire to understand the ecological mechanisms that underpin effects of environmental change on bigeochemical cycles and vegetation distributions in diverse settings so that we can better predict the consequences of human activities for the structure and function of ecosystems at the landscape scale. My goal is to derive knowledge that will contribute to our ability to manage ecosystems under changing conditions. I encourage systems-based approaches to science and interdisciplinary perspectives in my lab. My research efforts span multiple spatial scales, from microbes to landscapes, and take advatage of various tools, from lab assays to computer-based simulation and process models.

Current Students
Luis Andino

Luis Andino, M.S. Student, 2016 - present

Luis earned a B.S. degree in Socioeconomic Development and Environmental Sciences from Zamorano University, Honduras. His research focuses on the relationship between surface topography, subsurface drainage, and dissolved reactive phosphorus losses in agriculturally dominated landscapes.

Matt Candeias

Matt Candeias, Ph.D. Student, 2015 - present

Matt earned a M.S. degree in ecology from SUNY Buffalo State. His research focuses on investigating niche conservatism in plant communities through the lens of phylogeny and competition. The goal is to better understand how evolution and community composition relate to ecosystem functioning.

Mara Rembelski

Mara Rembelski, M.S. Student, 2016 - present

Mara earned a B.S. in environmental sciences from the University of Arizona. Her research addresses the combined effects of non-native grass invasion and prescribed fire on terrestrial carbon cycling in forested landscapes.

Ron Salemme

Ron Salemme, Ph.D. Student, 2015 - present

Ron earned his B.S. in Forestry from Humboldt State University and his M.S. in Natural Resources and Environmental Sciences from the University of Illinois. His work focuses on the interactive effects of non-native grass invasion and prescribed burning on tree regeneration, and prescribed burning effects on carbon cycling in eastern deciduous forests.

Sam Stickley

Sam Stickley, Ph.D. Student, 2015 - present

Sam earned a B.S. degree from Colorado State University and a M.S. degree in Environmental Studies from Virginia Commonwealth University. His research uses geospatial data to assess how landscapes and ecosystems are being affected by anthropogenic stressors and climate change. His goal is to prioritize conservation efforts by better understanding the distribution of species across dynamic landscapes.

Tyler Refsland

Tyler Refsland, Ph.D. Student, 2013 - present

Tyler earned a B.S. degree from St. Olaf College. His work focuses on climate change and plant water relations in forested landscapes managed with prescribed fire. Personal website

Matt craig

Matt Craig, M.S. Student, 2011-2014

Matt received a B.S. degree from Augustana College. His research addressed the effects of exotic plant invasion on carbon and nitrogen cycling in temperate forests. Matt is now a Ph.D. student at Indiana Universty in Bloomington.

Jinna Larkin

Jinna Larkin, M.S. Student, 2010-2014

Jinna received a B.S. degree from McGill University. She used remote sensing imagery to examine temporal changes in water quality parameters in the Hudson River. She is curently employed as a GIS analyst.

Jackie Krall

Jackie Krall, M.S. Student, 2010-2012

Jackie studied the role of seed removal in exotic plant invasions in long-leaf pine ecosystems. She is currently employed as an environmental consultant by Apex Environmental Consultants in Lenexa, KS.

Corinne Block

Corinne Block, M.S. Student, 2009-2011

Corinne studied the effects of hemlock loss on nitrogen and phosphorus cycling along a nitrogen deposition/availability gradient in western North Carolina. After finising her degree, Corinne spent three years working as a technician at the USDA Forest Service Coweeta Hydrologic Laboratory in Franklin, NC. She now lives in Bend, OR.
