Research interests



Biological invasions

Biological invasions have major ecological and economical consequences, especially by disrupting trophic cascades and by homogenising biodiversity. Each invasion process is characterised by three stages: the introduction, the establishment of viable populations, and their proliferation in the new environment. Demographic, ecological and genetic mechanisms occur in each stage.

Our researches aim at studying biological invasions in social insects and lie on a combinatory approach including genetic, behavioural, chemical and ecological data.


Life-history traits of humivorous termites

Humus-feeding termites are abundant and ecologically important in soils of neotropical rainforests. However, their reproductive and dispersal strategies remain poorly known.

Our interests are directed towards investigating population genetic structure and reproductive and dispersal strategies of a guyanese Cavitermes species.
