Education:

My research emphasizes (1) the measurement, modeling, and management of uncertainty and risk for non-point source pollution of surface and groundwater; (2) the characterization and estimation of field-scale variability for precision farming; (3) the evaluation of alternative farm management strategies for improved soil quality and sustainability; and (4) evaluation of policies for soil and water resources.

Classes:
ES 3131 Environmental Physics
