About me

I am a postdoc at the Institut Camille Jordan at the Université Claude Bernard Lyon 1, with the Probabilités, statistique, physique mathématique (PSPM) team, with Christophe Poquet.

The title of my PhD thesis is Collective behaviour of active particles with mean-field interaction.

Research

I am interested in mathematically understanding the emergence of collective behaviour. Examples of this emergent behaviour are lane formation in groups of ants or pedestrians, or flocking in birds.

I focus on analysis and probability.

In my work I have studied a model for lane forming ants, together with my co-authors (see Publications for links to papers).

The first is an aggregation type behaviour. The second is the formation of an ant lane. In the papers, we explain how this is related to lane formation and ant antennas.
