Agricultural water, groundwater sustainability, and land-use transitions.

I develop data-driven models and decision-support tools to evaluate agricultural adaptation to water scarcity, with emphasis on groundwater-dependent regions, irrigation technology, crop choice, and land-use transitions.

Research Profile

My research focuses on how agricultural systems adapt to water scarcity, groundwater depletion, and changing economic conditions. I combine agricultural economics, geospatial analysis, hydro-economic modeling, and optimization to evaluate irrigation transitions, crop choice, land-use change, and decision-support strategies.

Groundwater Sustainability

Studying aquifer depletion, irrigation capacity decline, and agricultural transition pathways in groundwater-dependent regions.

Irrigation Economics

Evaluating irrigation investments, pumping costs, crop profitability, and water-use decisions under changing hydrologic and economic conditions.

Geospatial Modeling

Integrating GIS, remote sensing, county-level crop data, climate variables, soil data, and groundwater datasets for regional agricultural systems analysis.

Decision-support Tools

Developing applied tools using Excel/VBA, Python, ArcGIS, and GAMS to support irrigation planning and agricultural adaptation analysis.

Featured Projects

Current and recent projects focus on irrigation transitions, bioenergy crop systems, groundwater conservation, and agricultural decision-support tools.
