Loblaw Chair in Sustainable Food Production

Sustainable agriculture, climate change, energy conservation, multiple cropping systems, organic agriculture, forage agronomy, closing nutrient cycles, nitrogen use efficiency, pasture management, and ethics in agriculture.

Research Interests:

Dairy cows

My approach to sustainable food production is to produce enough food to meet dietary needs today, while preserving productive capacity for future generations of people and other species. This is within the context of healthy soil, clean air and water, and regenerative energy to support resilient farming and fishing communities.

My research involves collaborative inquiries across disciplines. My training and specific contributions pertain to multiple cropping systems, nitrogen use efficiency, forage agronomy and pasture management.
