Introduction

Research focuses on determination and quantification of the mechanisms and factors controlling the degradation, movement, and activity of pesticides and their metabolites in soil; and to use this knowledge to reduce pesticide use by increasing herbicide efficacy in agricultural production systems, and to decrease the risk of ground water contamination.

Research Area(s)

Biogeochemistry
Contaminant Hydrology and Water Quality
Environmental Chemistry
