Research Statement

New technologies such as yield monitor system, satellite imagery and UAVs are generating large sets of data that can be used as a valuable addition to precision agriculture decisions. My work with the Nutrient Management Spear Program involves analyzing these datasets using advanced hierarchical statistical model as well as developing methodology and protocol to use and process these datasets for agricultural decisions.
