Soil Chemistry and Biogeochemical Interfaces

Dr. Jared L. Wilmoth leads the Soil Chemistry and Biogeochemical Interfaces research group in the Department of Environmental Science and Technology at UMD (College Park). The research focuses on understanding the fundamental, mechanistic, connections between environmental soil systems, their biogeochemical cycles, and the Earth’s climate. Current work examines how soil redox conditions and climate-driven perturbations interact in different soil environments using high-resolution chemical and biomolecular characterization techniques. Critical abiotic and biotic pathways that span mineral, microbial, organic matter, and rhizosphere interfaces are regulated by these interactions that operate over different spatiotemporal scales. Current research efforts seek to investigate and disentangle these processes in field and laboratory studies to better understand their relationship with global carbon (C) cycling and environmental sustainability. Key areas of interest in soils research include redox transformations, soil organic matter transformations, changes in soil microbiome function and activity under redox-oscillating conditions, and the combined use of different experimental and modeling approaches to link the small scale of soil biogeochemical interfaces to the large scale of Earth systems. The overall research approach is highly collaborative and inter/multi-disciplinary in nature to explore soil chemistry and biogeochemical interfaces in different environments and to improve our understanding of their global impact.
