I- Project on the zebra finch’s
acoustic communication network.
In collaboration with Nicolas Mathevon, I’m trying to answer
to three important questions of social networking:
(1) Knowing who is who: what are the acoustic processes of individual
recognition between network’s members?
(2) When one’s behavior is influenced by his network:
does the social context influence zebra finches’ communication
(3) Experiencing changes in the network’s configuration:
do communication behaviors depend on network’s structure?
This project has been funded by an ANR grant, and has involved

This project has involved 2 PhD students under my supervision

As well as several postdoc researchers (Alexandra Hernandez,

II- Project on the acoustic partnership between zebra finch
The monogamous pair bond in birds represents
a real partnership: male and female work as a team during chicks
rearing and synchronize numerous activities. The coordination
between mates is reached by constant communication between the
partners. In this framework, my research objective is to understand
the acoustic communication processes linked to the strong social
partnership of the monogamous pair-bond in the zebra finch (Taeniopygia
This project is currently funded by the University
of Saint-Etienne (International projects funds), the CNRS and
the Fyssen foundation (postdoctoral fellowship to Mylène
I'm currently in charge of the
University courses that prepare to the French national exam
to become High-school teacher => Classe de Préparation

I'm also teaching ethology and neuroethology to Master students,
as well as physiology at undergrad level (licence).
