Education
- PhD/MS Soil Science/Biometry, University of Wisconsin–Madison, 2002
- MS Geography, The Pennsylvania State University, University Park, 1997
- BS/BA Electrical Engineering/Rhetoric, Univ. of Illinois, Urbana-Champaign, 1988
Teaching
My instructional responsibilities include: (1) an undergraduate course on world agricultural systems (SoilS/CropS 360) taught every fall; (2) a graduate-level Environmental Spatial Statistics course taught in the fall in even years; and (3) an advanced undergraduate course on Soil Geography that will be offered in the fall of odd years. The last course will be taught for the first time in 2009 and represents a significant revision of the Landscape Pedology course I have taught for the past six years. Both the spatial statistics and soil geography courses are very “hands on” with extensive computer and field lab work (for Soil Geography).
Research
My research is focused on measuring, modeling and explaining the spatial variability of soil properties and processes at hillslope to regional scales. Currently that research is focused on (i) linking the evolution of central African landscapes to the spatio-temporal characteristics of contemporary dambo wetland methane emissions; and (ii) measuring agricultural soil carbon sequestration in the northern Rocky Mountain region. In pursuing this research, I make extensive use of digital terrain modeling, spatial statistics, and proximal soil sensing techniques.
