About UsDr. Emery is one of the world’s leading experts in the study of plant hormones. In particular, he works on a family of hormones, the cytokinins, which are notoriously difficult to analyze and which are potent regulators of plant development even when present at extremely low concentrations. Prior to coming to Trent in 2000, he completed post-doctoral research in Australia working on hormonal control of fruit set and seed development in chickpea and lupin and in France examining nitrogen and carbon metabolism in field peas. In his work with legumes he is studying how the plants biochemically pull themselves together as a means of determining how to create bigger, more stable yields. The end users of research findings would be breeders of plants who he could give direction for making better varieties of each plant.

Lab NewsApril, 2017 - To branch or not to branch? Shade, ABA and auxin - Dr. Thien Nguyen and Prof. Neil Emery co-authored an insight paper that accompanies the groundbreaking research on ABA as the earliest upstream inhibitor of apical dominance, recently published in Journal of Experimental Botany.
December, 2016 - Research at Trent in Dr. Neil Emery’s lab highlighted in exhibition titled “Pulses: The Ideal Partner” on loan from the Canada Agriculture and Food Museum in partnership with Pulse Canada (Trent University News & Events)

A New Bio-fertilizer for Farmers
May, 2016 - "Researchers at Trent University have discovered beneficial plant bacteria that could be used to produce more field crops like soybeans without having to farm additional land." (AgInnovation Ontario)
May, 2016 - "Neil Emery is after the freaks. The high-performing bacteria kind, that is. The Trent University professor is developing a new bio-fertilizer for farmers to increase yields and use less irrigation and fertilizer." (Toronto Star)
February, 2016 - “By testing and using carefully selected strains of bacteria, we’ve found a natural soybean growth enhancer that, with targeted application, can produce plant growth hormones that act as a nutrient vacuum, stimulating transport of metabolite building blocks to specific areas of a plant,” says Dr. Anna Kisiala, member of the research team.
