Principal Investigator

Stuart is an associate professor in the Department of Natural Resources and the Environment here at UNH. His research examines how soil organisms interact with their environment to regulate ecosystem processes such as nutrient cycling, organic matter turnover, trace gas emissions, and productivity. This research encompasses multiple spatial scales and lies at the interface of soil ecology, biogeochemistry, and ecosystem science.

Emily Austin |

Emily E. Austin is a postdoctoral research fellow working on the "cover crop root and shoot contributions to soil organic matter" project. Her research interests include rhizosphere carbon cycling, microbial structure and function, and decomposition. She earned a PhD in 2013 from the University of Tennessee in Dr. Aimée Classen's ecosystem ecology lab. Her doctoral research focused on the effects of climatic warming on wood decomposition and wood decomposing fungal communities.  Prior to her doctoral work, Emily worked as a post- baccalaureate research fellow at Oak Ridge National Lab and as a NSF REU student at Harvard Forest at Hampshire College.


Amanda Daly |

Amanda’s fascination with soils sprang from a love for complex ecosystems, the mysteries of the invisible, and the booming local food movement in her home state of Vermont. Trained as an ecologist and molecular biologist, she aims her research toward improving understanding of our natural world to enable land-management strategies that maintain ecosystem health and productivity. She is also passionate about being of service to the broader community whether by supporting farmers, writing in accessible ways about science, bringing playful knowledge-building activities to K-12 classrooms, or encouraging future scientists from underrepresented groups to pursue careers in STEM.

Andrea Jilling

Andrea unearthed her interest in soils while studying botany and plant ecology at McGill University. After working on a series of vegetable farms for three years she resolved that far too many mysteries still lurk in our soils– how can we build fertile soils without sacrificing critical ecosystem properties? Can we manage cropping systems for long-term nutrient storage and short-term nutrient supply to crops? She now follows these questions as a PhD student, specifically researching how plant roots interact with both the living and non-living components of the soil environment to influence nitrogen (N) cycling.

Emily loves using quantitative tools to explore plant-microbe-soil interactions. As a PhD student in the Grandy lab, she integrates current theories in biogeochemistry, microbial physiology, and nutrient cycling in her work with the MIcrobial-MIneral Carbon Stabilization model (MIMICS). Prior to her graduate work, she studied engineering and ecology at Dartmouth College and worked as a technician in a pedogenesis lab at the USGS in Menlo Park, CA. In her spare time, she’s building a 200 sq ft tiny house on a trailer.


Lauren Breza | Lauren Breza

Lauren is a student in the Natural Resources and Earth System Sciences PhD program at the University of New Hampshire. In 2015 Lauren received her master’s degree from the Ecology and Evolutionary Biology at the University of Tennessee. Lauren’s general research interests lie within human disturbed ecosystems under a changing climate. Her PhD work focuses on soil ecology in agro-ecosystems and she is specifically interested in exploring ideas around nutrient cycling, plant-soil interactions, and soil microbial ecology in sustainable agricultural ecosystems. Her master’s research examined the impact of urbanization on the evolutionary trajectory of species diversity and phylogenetic diversity.


Nell (Eleanor) Campbell

Nell’s research focuses on advancing the understanding of mechanisms driving soil organic matter dynamics and terrestrial nitrogen cycling, and how these mechanisms are impacted by agricultural management practices and land use change. Her background is in bioenergy cropping systems, evaluating the role of different crop types and management practices in impacting soil carbon and greenhouse gas flux across the agricultural landscape. She has shifted over into temperate and tropical pasture systems, adding livestock as both a driver of ecosystem processes and as a metric for yields from a land area.  She primarily uses process-based ecosystem models (DAYCENT and DNDC) to represent, integrate, and test hypotheses, coordinating with experimental researchers and exploring advancing areas in data-model integration.

Bennett Thompson

Bennett became interested in soil and agriculture thanks to the farmers and local food advocates in his Iowa community. With a background in biology from Swarthmore College, Bennett’s master’s research investigates how agricultural management practices affect soil processes such as nitrogen mineralization, an ecosystem service that farmers depend on. He hopes that down the road, his basic research in the lab can help provide farmers with decision-making tools to boost productivity and sustainability. He is currently working with other members of the lab on the protocol for the N15 amino acid pool dilution studies.

Scott Greenwood
Lab Manager |

Scott is an environmental engineer whose main interests involve low impact remediation techniques and assessment of the bioavailability and transport of anthropogenic contaminants in the environment. Scott helps to manage several pieces of analytical equipment in Dr. Grandy’s lab including a Pyrolysis-GCMS for determining soil carbon chemistry; a traditional solvent injection GCMS Quadrupole for N15 amino acid pool dilution studies; and other C&N analytical instrumentation.


Karen Moran

Karen began her studies in agriculture at Zamorano University with a focus on production but her interests have extended to work on the interface of climate change, poverty and policy making. Her aim is to conduct research that integrates agricultural sustainability and natural resources management to support healthy agroecosystems for economic development and poverty reduction. She has broad experience in food production, food science, environmental science and agribusiness and she would like to work in an institution, government or private, to conduct research and help develop policies relevant to sustainable development.
