I am starting a research program aimed at finding solutions to agronomic problems faced by farmers in eastern and northern Ontario. My research interests focus on the agronomy and crop physiology of field crops (spring cereals, corn, soybeans and legumes). Unique to this research program is a built-in collaboration with the scientific staff and facilities located at the Winchester, New Liskeard and Emo agricultural research stations.
