  • Botany
  • Ecology
  • Fungus

Marc St-Arnaud mostly deals with Rhizosphere, Root microbiome, Olpidium, Microbial ecology and Phytoremediation. His Rhizosphere study combines topics from a wide range of disciplines, such as Canola, Agronomy, Plant nutrition and Fusarium merismoides. The various areas that Marc St-Arnaud examines in his Root microbiome study include Olpidium virulentus, Olpidium brassicae and Nutrient.

His Microbial ecology research includes themes of Willow, Basidiomycota, Botany and Soil water, Soil microbiology. His work on Salix purpurea as part of general Botany research is frequently linked to Fungal genetics, bridging the gap between disciplines. Abiotic component is closely connected to Soil contamination in his research, which is encompassed under the umbrella topic of Phytoremediation.
