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

Area of Expertise:
Micro- to macro-scale biogeochemical processes involved in soil carbon and nitrogen cycling. Current research focus is on understanding the role of soil pores in micro-scale processes driving soil carbon sequestration and greenhouse gas emissions; and the role of the interactions between land use and management, soil properties and topography for spatial variability of soil carbon sequestration and greenhouse gas emissions across agricultural fields and landscapes.
