Research Interests

My past (PhD project) and present (postdoc) research relate to two aspects of plant ecology: community and functional ecology. More precisely, I’m interested in describing and predicting patterns of species and functional diversity in response to various environmental and land use changes.

Doctoral Research

Predicting community structure from plant life history traits: a maximum entropy model.

The objectives of my PhD were: 1) to study the relationships between the composition of traits found in different communities and underlying environmental gradients; 2) to determine the capacity of a recently developed model to predict the relative abundance of species in different environment based on these relationships; 3) to use this model to determine a list of parsimonious traits for future research
