Agathe Leriche’s recent research aims to identify the drivers of plant biodiversity around the Mediterranean basin and whether and how the structure, composition and dynamics of natural communities are affected by global changes (long-term and large spatial-scale patterns and processes). It seeks to integrate functional ecology, evolutionary ecology and biogeography to describe and explain how several facets of biodiversity (e.g., functional diversity versus phylogenetic diversity) are distributed in space. Her research aims to have implications towards a conservation framework.

She has also performed several researches devoted to ecology of invasions, and in particular the assessment through modelling approaches of biosecurity risks associated to insect pests, pathogens and weeds. She has been member of the Australian CRC (Cooperative Research Centre for National Plant Biosecurity) and is member of Pest Risk Mapping Group (international panel of modellers focusing on pest risk modelling practice). She still has interests in developing and refining ecological methods for estimating pest risk, and post-border pest management.

She is member of the Climond team involved in the not-for-profit initiative intending to share specially formatted environmental data for use in ecological modelling (species distribution modelling, species niche modelling, pest risk analysis and pest risk assessment, species vulnerability modelling, assessing biofuels and other crop potential and threats, climate change research ;
