Current research and/or projects

I am studying Canada’s subsurface geology using seismic methods, a field of geophysics. This method uses sound waves to image the internal structure of the Earth’s crust and give information about the geological materials that forms it.

Importance of my research

My work is applied to different geological problematics such as the environmental impacts of permafrost degradation, geohazards, resource evalution and the determination of the offshore extent of the Canadian landmass.
