    À PROPOS

    Le Dr. Sanchez est Professeur Associé à l'Université d'Ottawa. Son expertise est liée au développement de matériaux en béton durables et à la durabilité du béton, en particulier au diagnostic et au pronostic du béton affecté par les Réactions de Gonflement Internes (Internal Swelling Reactions - ISR). Il a co-écrit plus de 100 publications référencées sur ces sujets et a contribué au développement de protocoles de test standard, ainsi que de modèles descriptifs, empiriques et numériques pour la conception et l'évaluation du béton. Le Dr. Sanchez est un participant actif dans plusieurs comités nationaux et internationaux liés à la durabilité et à la durabilité du béton, et il est actuellement le vice-président du RILEM TC AAR - Alkali-aggregate mitigation in concrete. Le Dr. Sanchez est relecteur pour plusieurs revues importantes dans le domaine et a reçu des prix très prestigieux tels que la bourse de doctorat VANIER (2010), le Prix de recherche pour jeunes chercheurs du CRSNG (2016), la subvention Exploration du FONREF (2019) et le distingué Prix de recherche précoce du ministère de l'Ontario (ERA) en 2021.
