Research topics

My research work focuses on the remote sensing of natural plant ecosystems such as forests and wetlands. My main focus is the development of tools for the analysis of 3D data from terrestrial LiDAR in the context of forest inventories (LiDAR is particularly well suited to measure parameters that are otherwise difficult to obtain). I am also looking to improve the ability to measure forest cover with airborne LiDAR and other remote sensing tools such as optical/infrared satellite images of all spatial resolutions. Finally, I spend some time on studies on ecosystem conservation issues and the use of geomatics tools for watershed management.
