EducationResearchSome 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.QCBS studentsThi Dieu DINHPh.D. Meghana ParanjapePh.D. safidy RandrianiainaPh.D. Ghazaleh SeratiPh.D. Leila Yousefizadeh NaeniPh.D. Camille Dionne-PierreM.Sc.
