Erin Brooks research focuses on the site-specific management of complex ecosystems through extensive field-based experimentation and process-based spatially-explicit models. He has been the PI or Co-PI on numerous large interdisciplinary grants including the USDA funded REACCH, LIT and ISAID grants, and has been highly active in collaborative research with the USDA-ARS and USDA-Forest Service. This work has included fundamental landscape level hydrologic field experiments examining surface and subsurface nutrient transport, GIS-based distributed hydrologic, soil erosion, and crop modelling, in-stream sediment transport and nutrient cycling, forest fuel management and post wildfire mitigation treatments, spatial patterns in crop response and crop nitrogen uptake with remote sensing and modeling. His research has been conducted in widely diverse ecosystems including dryland agroecosystems, snow-dominated management forests, rangeland, tropical agricultural and forested ecosystems, perennial grasslands, deciduous forests and mixed urban environments. He has authored over 80 publications in scientific peer-reviewed journals.
