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

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


Location:

Plant and Soil Sciences Building,
1066 Bogue St., Room 376
East Lansing, MI 48824

Education:

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.
