Short Bio

During his 35 years at McGill Donald L. Smith (Distinguished James McGill Professor) has conducted research in the production and physiology of crop plants, with an emphasis on plant-microbe interactions, most recently, within the context of biofuel feedstock production. Specific areas of research have been: nitrogen metabolism, nitrogen fixation, low temperature stress and legume nodulation, methods for injection of metabolites into plants, cereal production, plant growth regulators, intercropping, inter-plant competition, plant-microbe signaling, plants and climate change, biofuel crops, cannabis, crop stress responses and biochar as a soil amendment. Work on microbe-to-plant signals and plant stress responses has is leading to climate change resilient crop production systems. He has trained 82 graduate students, ~2/3 at the Ph.D. level, published >350 papers, generated thirteen patents, started a spin-off company (Bios Agriculture Inc.), and commercialized technologies now applied to ~100 million ha of cropland per year. He has been cited more than 14,000 times and his current H index (Research Gate) is 61. He has been principal investigator on research grants totaling ~$80 million. He currently led BioFuelNet, which was just finished a 5-year cycle of funding ($50 M), which led to an additional $10 M to fund Biomass Canada through AAFC

Research interests

Dr Smith's research interests are in the area of crop eco-physiology. They can be broken down into several specific areas of activity. One of these is the use of signal compounds to improve legume nitrogen fixation under environmental conditions inhibitory to symbiosis development. This work has led to a number of publications, patents, and the establishment of a spin-off company. A second area is the use of plant growth promoting rhizobacteria (PGPR), and signal compound produced by them, to increase the growth and yield many crops. This led to the isolation of several new PGPR strains and the isolation of a material, produced by a PGPR, that causes direct stimulation of plant growth. A third area of research is the use of the signal compounds produced by rhizobia during the establishment of the rhizobia-legume symbiosis to directly promote plant growth. Fourth, research is methods to increase the sequestration of CO2 from the atmosphere into crop plants, including the use of biochar, for ultimate sequestration into soil, or for use in bioproducts. This is linked to the utilization of crop plants in greenhouse gas management, including use of lignocellulosics produced by crop plants as biofuel feedstocks.
