This research is conducted in an interdisciplinary manner, on long-term study sites, seen as complex socio-ecological systems. ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ <a name="_Toc492022468"></a><a name="_Toc460584103"></a><a name="_Toc199735493"></a><a name="_Toc199694041"></a><a name="_Toc199692071"></a><a name="_Toc199671575"></a><a name="_Toc199671221"></a>Diplomas: ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- 2008 Habilitation to direct research (HDR) in ecology, INP Toulouse 1999 PhD thesis from the University Paul Sabatier in Toulouse (UPS), Specialization: Forest Ecology 1989 Agricultural Engineer from the Ecole Nationale Supérieure d'Agronomie de Toulouse (ENSAT), Specialization: Plant Protection.
