Meet the Soil, Environmental and Atmospheric Sciences Faculty

Stephen Anderson

Stephen H. Anderson, Ph.D.

Professor of Soil Science and Department Chair
Soil, Environmental and Atmospheric Sciences

Education

  • Ph.D. 1985, North Carolina State University

Research

  • Soil physics, X-ray tomography of soil systems

Research Description

Anderson's primary research interests include: evaluation of soil management effects on soil hydraulic properties; development of X-ray computed tomography and microtomography techniques for assessment of pore-scale soil properties and processes; and using simulation models to evaluate effectiveness of conservation practices at the watershed scale. Soil properties evaluated with X-ray tomography include macropore and mesopore size distributions and characteristics, pore continuity, and pore tortuosity; all critically important for transport of water, air and solutes in soil systems. Fractal and fuzzy logic techniques are applied to quantify pore-scale variability of biopores.
