My primary interest focuses on understanding how different environmental variables, such as water temperature and flow, affect the habitat and physiology of key fish species. My research aims to generate knowledge about aquatic ecosystems at risk of thermal degradation and to inform on stream restoration strategies and aquatic resources management, especially in the context of human impacted systems and climate change.


2013 – Ph.D. in Water Sciences, INRS Eau Terre Environnement, Québec, Canada.

2006 – Masters in Water Sciences, INRS Eau Terre Environnement, Québec, Canada.

2003 – Specialized degree in Wildlife & Habitats Management, UQAR, Rimouski, Canada.

2002 – Bachelor in Biological sciences -Ecology and Environment, Montréal University, Montréal, Canada


Dr. Ouellet completed her BSc in Biological Sciences at the University of Montreal and finished a specialized diploma in habitat management at the Université du Québec à Rimouski in Canada. She then undertook a MSc and PhD at INRS Eau Terre Environnement and worked in coordination with provincial and federal agencies. Her master project focused on the impact of water level management on biological indicators such as wetlands and muskrats for an international study on the St. Lawrence River. For her PhD, she developed a 2D water temperature model and fish habitat model to study the role of elevated water temperatures in a massive fish kill in the St. Lawrence River. She also conducted experiment to understand on thermal stress can affect fish immune system.

In 2015, Dr. Ouellet moved in Pennsylvania to work as a postdoctoral researcher at the Stroud Water Research Center. She worked on thermal dynamics in rural and urban areas, fish thermal habitat and stream restoration. Her work aimed the restoration of habitat for cold water fish species and to understand how riparian restoration and thermal stress affect the interactions between the different aquatic communities.
