Mon laboratoire se spécialise dans l’étude de la stabilité à long terme des écosystèmes. Plus spécifiquement, nous cherchons à comprendre les facteurs de stabilité et d’instabilité des fonctions et services écosystémiques des milieux humides et aquatiques dans un contexte de changements environnementaux. Nous nous intéressons à la fois aux changements à long terme (siècles –millénaires) et aux changements à moyen terme (années – décennies). Pour ce faire, nous utilisons diverses techniques, incluant la micropaléontologie, les mesures biogéochimiques, les inventaires végétaux et la modélisation.

Un autre axe de nos recherches couvre les impacts environnementaux des activités de recherche scientifique. Nous nous intéressons ainsi aux concepts d'empreinte carbone et d'empreinte azote, appliqués aux institutions.

Professeure au département de géographie de l'UdeM depuis 2012. Auparavant, elle réalise un post-doctorat à l'Université du New Hampshire et un doctorat à l'Université McGill. Ses recherches se concentrent sur les impacts des activités humaines sur le fonctionnement des écosystèmes naturels, en particulier des milieux humides. Julie Talbot a aussi un intérêt envers la quantification des impacts environnementaux des activités des universités et de la recherche, en particulier la mobilité académique.
