My research integrates processes across multiple scales—from individual sediment particles to watershed‑level dynamics—and bridges fundamental hydrological theory with experimental and field investigations to advance sustainable and adaptive agroecosystems. I have made foundational contributions to sediment transport theory by expanding H. A. Einstein’s stochastic framework. This work explains the intermittency of soil and sediment fluxes by quantifying grain resting times, travel times, and travel velocities, improving our ability to predict downstream sediment migration.
Using a landscape‑oriented approach to soil organic carbon (SOC) dynamics in intensively managed systems, I have combined field observations with modeling to reveal how selective soil mobilization, oxidation, and intermittent transport drive SOC enrichment and depletion across landscapes. This work provides a new perspective on carbon redistribution. I have also developed an enhanced Bayesian fingerprinting framework to characterize sediment source dynamics, offering a paradigm shift in linking terrestrial processes with in‑stream and coastal processes for more accurate sediment and carbon/nutrient budgets.
My current research focuses on regenerative agriculture and strategies to improve input‑use efficiency for American producers. While major national goals—reflected in the USDA strategic plan—emphasize sustainability and resilience, agile solutions for production systems remain underdeveloped. My vision is to lead transformative, systems‑based research on sustainable food, water, and energy production that is environmentally sound, socially acceptable, and economically competitive. Drawing on my background in Critical Zone Science and adaptation strategies, I aim to establish NLAE as a world‑class hub addressing rural community resilience through convergent research, dynamic predictive tools, field‑based capacity building, and knowledge transfer to stakeholders.
Before joining USDA‑ARS at the National Laboratory for Agriculture and the Environment, I served in both academia and industry. My academic appointments included Washington State University, the IIHR‑Hydroscience and Engineering Institute at the University of Iowa, and the University of Tennessee. Across these institutions, I built a strong record as a mentor, instructor, and researcher. At Tennessee, I directed the Tennessee Water Resources Research Center, guiding statewide water initiatives such as TNH2O. At Iowa, I established the Clear Creek Observatory, one of the ten Critical Zone Observatory sites in the United States. At Washington State, I revitalized the Albrook Hydraulics Laboratory.
My professional service includes serving as Editor‑in‑Chief of the ASCE Journal of Hydraulic Engineering and participating on editorial boards for Water Resources Research, the International Journal of Sediment Research, and the Journal of Soil and Water Conservation. In industry, I served as senior advisor and research engineer with Northwest Hydraulic Consultants, leading major international projects and watershed research efforts.
I have secured more than $37 million in funding from federal and state agencies—including USDA, DOE, NRCS, NSF, NAS, USGS, DoD, and ONR—as well as private foundations. I have also contributed to numerous ASCE and AGU committees, and served on review panels for NSF, DOE, USDA‑NIFA, and NIWR/USGS.
