Claudie Ratté-Fortin received her doctorate in water science from the INRS Eau Terre Environnement Research Centre, working with Professor Karem Chokmani. Her project looked into water quality problems in our aquatic ecosystems, and more specifically, at recurring blooms of cyanobacteria. Claudie’s work has led to the development of a regional nonstationary frequency-analysis model that makes it possible to assess restoration scenarios for water bodies, factoring in changes in climate or land use. She is doing a postdoctoral fellowship with Professor Jean-François Plante, focussing on modelling extreme natural events such as flooding, high- and low-water flows or episodes of toxic cyanobacteria. Her goal is to assess the potential of recent modelling approaches, like machine-learning algorithms, to account for the complexity of some natural phenomena that continue to be difficult to explain adequately using standard approaches. She is also involved in the Info-Crue project, with Professor Jonathan Jalbert of Polytechnique Montréal, to update the mapping of the flood-risk areas of southern Quebec’s rivers while accounting for climate change.
