Education1998 Ph.D., Soil Science, Colorado State University, Fort Collins, Colorado. Dissertation: 'Aggregate and Soil Organic Matter Fraction Dynamics in Agroecosystems' 1995 M.Sc. Bio Engineering, Katholieke Universiteit Leuven, Belgium. Major: Soil Science; Minor: Tropical Agriculture. Thesis: 'Soils and Land Use in the Eastern Region of South Vietnam and Lam Dong Province'
Research InterestsMy research interests focus on the feedbacks between ecosystem management options (e.g., tillage, cover cropping, green manuring, sustainable farming, and grazing), global change (e.g., elevated CO2 and climate change), and biogeochemical cycling. More specifically, I study the complex interactions between soil (e.g, structure, texture and mineralogy), plants (e.g., diversity, nutrient uptake, and root growth), soil biota (e.g. fungi, bacteria, and earthworms), and the carbon and nitrogen cycles
Areas of EmphasisAgricultural Ecology
 Ecosystems and Landscape Ecology
