Ecosystem Ecology & Remote Sensing

I have been introduced to remote sensing while I was a Marie Curie fellow at CSIRO, Australia. Back to Europe, I developped research on the dynamics of arctic and mountain ecosystems with a growing interest in analyzing the decadal trends of greening in response to climate, land use changes and meteorological extremes (heat wave). We are using high and moderate resolution satellite imagery to track these vegetation changes from space.
