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.


Emily Oldfield

I am interested in how soil organic matter (SOM) contributes to soil function. Specifically, my research focuses on SOM’s contribution to the productivity and resilience of agricultural landscapes.


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. 


Graduate Students
Clara Pregitzer

Doctoral Candidate, 5th year

My research falls broadly within the fields of applied and basic forest ecology. I am interested in understanding how the urban context can influence forest structure and function and how to best manage complex and dynamic landscapes for the future. Currently I am using forest assessment data to guide forest management and restoration targets for New York City.

Dan Kane

Doctoral Candidate, 4th 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, 2nd 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, 2nd 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.


Alexander Polussa

Doctoral Student, 1st 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, 1st year

I’m interested in how people shape biogeochemical processes in urban ecosystems. Specifically, I’ll focus on how historic landscape modification affects nitrogen cycling in forests across New York City. 

Linda Schade

MEM, 1st year

Linda Schade joins Yale FES with a background in climate mitigation and adaptation policy development at the sub-national level in the U.S., Mexico and China. She has also worked to publicize the mitigation opportunity offered by short-lived climate forcers in the U.S. and Mexico. During her 30-year professional career, Linda has led or consulted on water quality, renewable energy, election integrity, and a range of other public policy issues. Ms. Schade has a Masters in Urban & Regional Planning from Cornell University (1994) and a B.A. in Political Science (1988). At FES, Linda is focused on scaling up carbon sequesteration as a critical component of the global response to climate change. 

Viola Taubmann

MEM, 1st year

I am interested in how ecosystem services can contribute to more sustainable agricultral practices. During my time at Yale FES I focus on land use and human impacts on landscapes, specifically in agro-ecosystems and agroforestry.
