My field of work is oriented towards the study and monitoring of our environment, including the use of remote sensing tools. In addition, I am interested in global climate change and indirectly in the physical phenomena that occur in the atmosphere. I am also developing methods for estimating, by remote sensing, the water equivalent of snow in a hydroelectric production context.
Satellite monitoring and estimation of snow cover, snow water supply and ground temperatures Thermal and microwave infrared data fusion Development of methods for monitoring the northern environment in the context of climate change Forest fire detection Atmospheric aerosol study and air quality monitoring by remote sensing
