Seismic reflection, seismic and physical properties of geologic materials

Current research and/or projects

I am studying Canada’s subsurface geology using a geophysical method named seismic reflection. 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. My work focuses on the processing and analysis of seismic reflection data to evaluate the potential of energy resources in Canada’s North. I also use seismic reflection to study the geological storage of CO2 and environmental risks associated with the exploitation of non-conventional energy resources.

Importance of my research

My work provides the detailed geologic context which is essential for the understanding of oil and gas systems. Also, my work helps to better understand the distribution of energy resources so the exploration strategies of the industry are more efficient and economic investments maximized.
