Lab Member Profiles

Mark Bradford

My work spans questions that address uncertainties in Earth system feedbacks to quantifying soil health outcomes and forest processes. I am primarily interested in how organisms and their interactions affect decomposition and soil carbon stocks.

Research Scientists
Steve Wood

Steve is a soil scientist in the Global Lands team of The Nature Conservancy and has a joint appointment as an Associate Research Scientist at Yale F&ES. He is working to develop cutting-edge science to support soil activities across The Nature Conservancy. He has an interdisciplinary background, with degrees in ecology, economics, and philosophy. Steve’s topical expertise is in soil and ecosystem ecology, sustainable agriculture, sustainability science, and statistical modeling.


Postdocs and Fellows
Annise Dobson

My research is motivated by forest conservation for all, particularly in urban and managed forests. I am interested in the role of soil fauna in community and nutrient dynamics within these ecosystems.


Meghan Taylor

I am an ecosystem ecologist interested in quantifying spatial and temporal variability in greenhouse gas emmissions in response to climate change. I use carbon flux measurements and isotope geochemistry across wetland and tundra systems to identify drivers of emissions and partition fluxes. 


Fiona Jevon

I am a forest ecologist who likes to ask questions about the link between above-ground and below-ground processes. I’m interested in the feedbacks that exist between plants and thier associated soil microbial communities, as well as the relationship between plant traits and carbon cycling.

Graduate Students
Dan Kane

Doctoral Candidate, 5th year

My research focuses on rapid quantification of soil carbon at landscape scales and how soil carbon could be managed to mitigate the effects of climate change on agriculture. I am the lead researcher on Quick Carbon (, a research project at Yale F&ES focused on developing tools to rapidly estimate soil carbon using VIS/NIR technology and machine learning.

Eli Ward

Doctoral Candidate, 3rd year

My research focuses on feedbacks between invasive plants, soil nutrient availability, and disturbance. Specifically, I am interested in studying the effectiveness of current management practices, such as invasive plant removal, on the restoration of soil processes and whether additional site treatments may be required to restore soil function and limit reinvasion. The systems that I work in are primarily forested and strongly influenced by human use, such as urbanization and land management. I am particularly interested in applications of my research for conservation and restoration.

Kristy M. Ferraro

Doctoral Candidate, 3rd year

I am interested in the ecosystem services provided by large mammals as well as the impacts of local or regional extinction. Working between the Bradford Lab and the Schmitz Lab, I explore the impact of migratory mammals on soil dynamics, nutrient cycles, and carbon storage through both field experiments and models.


Alexander Polussa

Doctoral Student, 2nd year

How are micro-organisms interacting with plants, macro-organisms, nutrients, and each other? I aim to look at how bacterial and fungal activity influences the micro-environment and, in-turn, the broader ecosystem!


Sally Donovan

MESc, 2nd year

How does land use change impact biogeochemical patterns and processes in urban areas? I’m studying the legacy effects of historical agriculture on carbon and nitrogen cycling in forested natural areas across New York City.
