Bethany Avera, firstname.lastname@example.org
Beth is a PhD student in the Graduate Degree Program in Ecology, in the Department of Soil and Crop Sciences. She is a soil ecologist with interests in mycorrhizal fungi, soil organic matter formation and stabilization, and nutrient cycling in managed and disturbed natural ecosystems. She earned her B.S. at Clemson University in Soils and Sustainable Crop Systems. Her Master’s research at Virginia Tech evaluated the success of tree plantings to re-establish soil biogeochemical processes on reclaimed surface mined land in southwest Virginia. Now, her PhD work focuses on evaluating the impacts of salvage logging beetle-killed lodgepole for bioenergy through analyzing logging residue removal on soil organic matter stocks and nitrogen retention and allocation.
Erika Foster, email@example.com
Erika is a PhD student in the Graduate Degree Program in Ecology, in the Department of Soil and Crop Sciences. She graduated from the University of Montana with a B.S. in Natural Resource Conservation and Management, with an emphasis on Terrestrial Ecology and a B.A. in Environmental Studies, focusing on the interaction between humans and the natural environment. Her wide range of interests from sustainable agriculture to climate change science to ecosystem restoration and soil-plant interactions all coalesce in the study of biochar. She currently works on part of a larger research project on adapting agricultural management strategies to drought, specifically looking at the effects of biochar amendments mixed with manure on plant growth, soil water holding capacity, soil C sequestration, and various other soil properties.
Sarah Fulton, firstname.lastname@example.org
Sarah is a PhD student in Soil and Crop sciences at CSU and a fellow of the NSF IGERT in Multidisciplinary Approaches to Sustainable Bioenergy. Sarah obtained an MPA from Columbia University’s School of International and Public Affairs. She is using stable isotopes to study the decomposition of roots and plant residue in agricultural systems, and assess the role of roots in carbon and nitrogen cycling and contributions to C sequestration. Her interests are in sustainable land use for agricultural and bioenergy crop production, and finding synergies between increasing production and decreasing environmental impacts. More specifically, she wants to understand how agricultural management practices and cropping systems impact soil nutrient cycling and carbon sequestration.

Michelle is a Research Associate at the Natural Resource Ecology Laboratory at Colorado State University. She got her bachelor’s degree in Environmental Studies at the University of Nebraska-Lincoln in 2000 and her master’s degree in Ecology at Colorado State University in 2007. She has worked on a variety of experiments studying soil organic matter dynamics and characterization with a focus on decomposition, temperature, and land use change. For the Cotrufo group, Michelle is studying litter decomposition with stable isotopes and black carbon quantification after fire.
Sarah Leichty, firstname.lastname@example.org
Sarah is a Master’s student in the Graduate Degree Program in Ecology, in the Department of Soil and Crop Sciences. She graduated from Iowa State University with a B.S. in Environmental Science with honors and a B.S. in Agronomy, with an emphasis on Soil Science and Environmental Quality. While working in the Sustainable Agroecosystems Group at Iowa State, Sarah developed an interest for understanding how nutrients cycle in various agricultural environments and what role this plays in managing agricultural systems for maximum productivity and environmental health. Sarah’s graduate research will focus on the formation of soil organic carbon under sprinkler-irrigated corn systems.
Samantha Mosier, email@example.com
Samantha is a PhD student in the Graduate Degree Program in Ecology, in the Department of Soil and Crop Sciences. She received a B.S. in Environmental Science at The University of Michigan. She then continued her education at Michigan Technological University where she graduated with a M.S. in Applied Ecology. Her Master’s research involved assessing the interactive effects of climate change and fungal communities on the decomposition of wood-derived carbon in forest soils. Her interests include using stable isotopes to understand the stabilization and decomposition of soil organic matter as well as climate change science and sustainable land use practices,. She is currently researching the sustainability of southern pine plantations for biofuel production by analyzing soil carbon stocks and greenhouse gas emissions in relation to plantation site characteristics, management, and land use history.
Yamina Pressler, firstname.lastname@example.org
Yamina is a PhD candidate in the Graduate Degree Program in Ecology and Natural Resource Ecology Laboratory. She received a B.S. in Environmental Management with an emphasis in plant biology from California Polytechnic State University, San Luis Obispo in 2013. Broadly, Yamina’s research interests include soil ecology, soil food webs, biogeochemistry, fire ecology, pyrogenic carbon, and science education. Her dissertation research lies at the intersection of soil biology, disturbance ecology, and biogeochemistry where she investigates the effects of wild and prescribed fires on soil food webs and implications for ecosystem carbon cycling. She is particularly interested in the role of pyrogenic carbon in soil organic matter dynamics and belowground functioning. Yamina has a passion for science education where she investigates the use of systems thinking in ecology courses and works with K-12 educators to develop soil ecology curricular materials for their classrooms. Yamina also coaches the CSU Soil Judging Team.
Matt Ramlow, email@example.com
Matt is a PhD student in the Graduate Degree Program in Ecology, in the Department of Soil and Crop Sciences. His undergraduate studies at Yale University concentrated on both the social and natural sciences exploring climate change policy and conducting paleoclimate research in a geochemistry lab. Upon graduating he worked in international voluntary and regulatory carbon markets focusing on carbon accounting, particularly within the agriculture and forestry sectors. This work lead to his increased interest in carbon sequestration in terrestrial ecosystems, GHG emissions from land use, nutrient cycling and climate change mitigation. Matt’s graduate research, working with the Bioenergy Alliance Network of the Rockies, will focus on the impacts of biochar soil amendments in both managed forest and agricultural ecosystems.
Katie is an MS student in the Graduate Degree Program of Ecology, in the Department of Soil and Crop Sciences. She graduated from the University of New Hampshire with a B.S. in Earth Sciences, with a focus on Climate, and a minor in Environmental Conservation and Sustainability. Her research interests include soil biogeochemistry, nutrient cycling, GHG emissions, and how climate change and mitigation schemes are impacting these. Her current research focuses on using stable isotope labeling to understand the effect of biochar on soil N cycling and plant N use efficiency in agricultural systems. Additionally, she is interested in science education and promoting underrepresented groups in science.
Jennifer Soong, firstname.lastname@example.org
