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.

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
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 their associated soil microbial communities, as well as the relationship between plant traits and carbon cycling.

Angela is a National Science Foundation Postdoctoral Fellow in Biology working on microbial -omic relationships with ecosystem functioning, in particular litter decomposition at macrosystem scales. She begins a faculty position at Syracuse in fall 2022.
Graduate Students
Eli Ward

Doctoral Candidate, 5th year

My research focuses on plant-soil interactions and their effects on carbon and nitrogen cycling and storage in forests. Specifically, my work investigates feedbacks between invasive plants, soil nutrient availability, and disturbance as well as the influence of mycorrhizal functional types on soil biogeochemical processes. Many of the systems that I work in are strongly influenced by human use, such as urbanization and forest management, and I am particularly interested in applications of my research for conservation and restoration.

Kristy M. Ferraro

Doctoral Candidate, 5th 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 Candidate, 4th year

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