Soil spatial variability at scales from micro-aggregates to landscapes; statistical and geostatistical methods of data analysis.


Ph.D.  University of Wyoming


General areas of expertise:

Spatial variability in agroecosystems as a function of landscape, topography, and soil properties. Studied my means of statistics, geostatistics and fractal/multifractal methods.


Research Interests:

Specific interests are understanding the role of soil structure, including properties and internal characteristics of soil aggregates, on intra-aggregate water, air, heat, and carbon fluxes; and the role of the interactive influences of land use and management, soil properties and topography on carbon spatial variability across agricultural fields and landscapes.
