# overview
My current research areas include crop ecophysiology, agroecology and water management of agricultural crops. My research integrates measurements by a variety of techniques such as remote sensing, simulation modeling, soil and boundary layer flux (CO2, water vapor, and greenhouse gases) measurements. It involves scaling up point measurements to the field and landscape scales using modeling and geospatial data. It also includes the development of decision support tools for irrigation management.  My other research interests include large scale agroecosystem studies addressing issues such as land use change, water sustainability, and climate change.
