Nicolas Reynier, PhD

Research Scientist

Actinide Hydrometallurgy

Current research and/or projects


After completion of my Chemistry degrees in France and a work experience in actinide separation for military nuclear applications, I completed a PhD at the INRS, Québec on contaminated soil remediation. I am working at CanmetMINING on radioactive wastes management and actinides separation chemistry.
