Research Interests:
1. Chesapeake Bay
Ecohydrological Modeling of Water Quantity and Quality in Watersheds: Development of datasets and modeling tools to simulate streamflow, sediment transport, nitrate and organic nitrogen, soluble and organic phosphorus, dissolved and particulate organic carbon, wetland water levels, and CH₄ emissions.
2. US Midwest
Upper Mississippi River Basin (UMRB) HUC-8 and HUC-12 Watershed-Scale Water Quantity and Quality Dataset: Includes measurements and simulations of streamflow, sediment yield, nitrate and organic nitrogen, soluble and organic phosphorus, dissolved and particulate organic carbon, tile-drainage discharge, nitrate and soluble phosphorus loads, and N₂O and CO₂ fluxes from agricultural landscapes.
3. High Plains
Dataset and Modeling Tool Development for Using Brackish Water as an Alternative Resource for Freshwater Irrigation in Southern High Plains Watersheds.
4. Great Lakes Basin
Modeling Climate-Driven Shifts in Stream Thermal Regimes across the Laurentian Great Lakes Basin: The Role of Rain-on-Snow Events.
5. International Collaborations
• Canada
Development of an Ecohydrological Model for Cold Regions with Seasonal Snow Cover: Simulation of Soil Temperature, Freeze–Thaw Dynamics, and Their Impacts on Hydrological and Biogeochemical Processes.
• Spain
Hydrological and Biogeochemical Modeling of Non-Perennial Rivers: Focusing on Carbon Dynamics and Fluxes.
• South Korea
Assessing Climate Change Impacts on In-Stream Carbon Cycling in South Korean Watersheds; Integrating Remote Sensing and AI/ML Techniques with Hydrological Models to Improve Predictive Accuracy and Reduce Uncertainty.
• China
Modeling the Impacts of Crop Management Practices on Water Quantity, Water Quality, and Crop Yield in the Yellow River, Hai River, Liao River and Songhua River Basins
