Delottier, Hugo

Postdoctoral Researcher


I’m a groundwater hydrologist mainly focused on modeling flow and transport processes in heterogeneous porous and fractured media. I've obtained my PhD in hydrogeology from Université de Bordeaux in France under the supervision of Prof. Alexandre Pryet where I mainly worked on model predictive uncertainty quantification and groundwater recharge processes. I have then been involved in a major regional integrated surface and subsurface modeling project in the southern Québec region (Canada) from 2018 to 2021, together with Prof. René Therrien. The main purpose was to investigate the potential effects of climate changes on regional groundwater resources. From April 2021, I’m working with Prof. Philip Brunner on explicit simulation of environmental tracers through the use of advanced numerical modeling methods to better inform complex alluvial geology.

Feel free to contact me if you have any questions related to my topics.
