What is the focus of your research?

I joined the Geological Survey of Canada (GSC) in 1989. My work focusses on the study of microscopic fossils.  Due to their rapid evolution, these organisms can efficiently constrain geological time (biostratigraphy) and help better understand the formation of sedimentary deposits and environments. The information on color variations and opacification of their organic components can also be used to establish the level of thermal maturation of organic matter in rocks and sediments.  This procedure is used to evaluate the hydrocarbon potential in a region of interest.

What is the significance of your research?

My dating activities contribute to establish the geological context essential for the understanding of hydrocarbon systems. In addition, they help to better understand the distribution of energy resources, thus increasing the efficiency of industry exploration strategies and resulting economic benefits.
