  • Research

    Some of my main interests include the study of wildlife habitats and of landscape fragmentation from a conservation point of view. I am developing ways to evaluate the characteristics and to gain environmental markers that allow us to test the impact of management practice, infrastructures and human activity on the state of ecosystems. I am also working on the multiscale characterization of ecological networks and corridors. My predilection tools include satellite imagery, geographical information systems and drones.
