Research

I investigate architectural and anatomical root traits in legumes ( Phaseolus sp.) and maize ( Zea mays ) and their integrated effect on water and nutrient acquisition using field, greenhouse, and laboratory physiology techniques. Root traits of research interest can improve crop yield under stress by increasing the metabolic efficiency of soil exploration and by placing roots in soil domains where limiting resources are most available.
