Vialatte Aude

Senior scientist

Associate director of Dynafor



Research interests :

I conduct researches on agroecology at landscape scale. I focus particularly on biological control ecosystem services in crop fields and forests. I combine evaluation of ecological processes and functions with surveys on agricultural practices and spatial modelling. I am strongly involved in different interdisciplinary studies combining (i) remote sensing imagery and ecological surveys, and (ii) socioecological approaches on perceptions of stake-holders in ecosystem services associated to biodiversity.

​I am in collaboration with the CSIRO of Brisbane (Australia), in particular with Hazel Parry ( ).

I am assistant director of the lab.

I am the leader of the SECOTEAM group of the lab ( )
