Dr. Marie-Pierre Létourneau Montminy’s career reflects a life-long commitment to research in phosphorus (P) and calcium (Ca) nutrition and metabolism. She developed or refined important research models such as depletion-repletion, nutrient and growth modelling and precision feeding. She was a pioneer in the study of the interactions between phytic P and Ca when using phytase, and highlighted the negative impact of Ca on P absorption despite its necessity in the diet to deposit P into bone. Dr. Létourneau Montminy earned her Ph.D. from Laval University and AgroParisTech followed by a 3-yr post-doc. She was recruited directly into a full professorship at Laval University and rewarded their confidence soon after with a Canada Research Chair Tier 2. She has published 138 referred papers, presented invited lectures throughout North America and Europe. She has trained 24 Ph.D. and 22 M.Sc. students. Dr. Létourneau Montminy her colleagues have recruited $24 million in research funding.
