Current research and/or projects

The focus of my research:

My research interests focus on structural geology and I am collaborating on diverse regional and thematic studies such as on the tectonic, structural and metamorphic evolution of orogenic belts. I am the author of many regional geochronological, geological mapping and compilation studies in the Canadian Appalachians. I am also involved in projects focusing on the structural controls and geological fingerprint of Phanerozoic and Precambrian orogenic gold deposits.

The significance of our research:

The results of our research contribute to a better understanding of the detailed geologic context essential to the decision making process in mineral and petroleum exploration and for the sustainable development of natural resources. Also, our work helps to reach a better understanding of the distribution of resources thereby increasing the efficiency of exploration strategies.

Research and/or project statements

Current Research Projects:

  • Orogenic gold along major fault zones: Key characteristics and analogies between Phanerozoic and Precambrian settings.
  • Banded iron formation-hosted gold deposits within the Superior (Musselwhite) and Churchill (Meadowbank) geological provinces.
  • Northern Appalachians geology.

Professional activities / interests

  • I currently supervise 2 PhD candidates at INRS-ETE (2011 to 2016).
