My research falls broadly in the area of sustainable agriculture. My approach is to integrate diverse disciplines such as Biophysics, Climatology, Hydrology, Genetics, Agronomy, and Soil Science to understand the overall agricultural systems and to improve decision-making across a broad spectrum of stakeholders, from the smallholder farmer in the developing world to the industrial producer and policy maker at all scales.
I am mainly interested in the ecosystem of row-crop production systems. Chemically intensive production requirements have raised serious concerns about the sustainability of these systems. Of particular importance is the ability to provide sustainable ecosystem services (crop production, carbon sequestration, and nitrogen conservation, in particular).
Key aspects of my approach include the following:
The understanding of the spatial and temporal variability aspects of the soil-plant-atmosphere system is at the core of my research. One of my main research goals is to develop new technologies and transfer knowledge to farmers to better manage this variability and to quantify the risk associated with the decisions they make in order to optimize economic and environmental outcomes.
