My research focuses on soil organic matter and soil health. Soil organic matter is widely recognized as an integral part of sustainable agriculture, soil health and ecosystem resilience. It is critical for soil function, providing a source of nutrients, substrates and energy for the microbial population. My research program is one which examines land use and ecosystem influences on soil organic matter (SOM) dynamics and their relationship with soil fertility and carbon cycling in both the lab and field settings. I believe very strongly in the need to translate innovative research into practice. I am eager to take on graduate students and form a core, collaborative research team.
Quantifying Structural Stability of Agricultural Soils in Ontario
Soil compaction and surface crusting degrade soil structure, reducing aeration and root penetration, and ultimately impacting crop performance. With the trend towards larger farms, more massive equipment and increasing unpredictability of climate, the …

Soil organic carbon content: Decreases partly attributed to dilution by increased depth of cultivation in southern Ontario
Researchers analyzed soil organic carbon contents and depths of Ap horizons (i.e., cultivated topsoil) from Ontario soil survey reports from 1950 to 2019.
