I have dedicated myself to unraveling the complex interactions between soil, plants, and the atmosphere. My primary research interest lies in investigating the role of cover crops in mitigating greenhouse gas emissions and enhancing carbon sequestration in agricultural systems. I am particularly focused on understanding how different cover crop species, management practices, and soil conditions influence the exchange of carbon dioxide, methane, and nitrous oxide between the soil and the atmosphere By comprehending the dynamics of greenhouse gas emissions and exploring innovative approaches like cover cropping, I aim to provide practical solutions for reducing agriculture’s environmental footprint. I am driven by a deep concern for the profound impact of human activities on the planet’s climate system and I am committed to developing sustainable agricultural practices that mitigate climate change while maintaining agricultural productivity
Long term micrometeorology study of greenhouse gas emissions in agroecosystem
Active
One of the proposed strategies to mitigate CO2 emission from agroecosystems is by increasing terrestrial uptake of CO2 through crop diversification. Diversified corn-soybean crop rotations extend the amount of time that land is under plant cover, and may offset carbon losses that would otherwise occur during the spring and fall periods. The ongoing study at the Elora Research Station seeks to compare the net carbon balance of a simple rotation (corn–soy–soy) to a diversified rotation that includes winter wheat and cover crops (corn/cover crops-soy-winter wheat/cover crops)

Nitrogen used efficiency in vegetable farming in dry regions
Past

Insufficient knowledge about soil nitrous and nitric oxide (N2O and NO) emissions from vegetable production limits our ability to constrain their atmospheric budget. Carrots (Daucus carota) are a globally important, heavily managed and irrigated, high-value horticultural crop. Although intensively fertilized carrots may be an important hot-spot source of N2O and NO emissions, we have little information on the response of soil N2O emissions to fertilization and no information on the NO emissions response https://doi: 10.1371/journal.pone.0287436
