Collective Dynamics in human Crowds

I'm a research scientist, and I study the behaviour of human crowds. I try to understand how people interact with each other, and how these interactions generate collective crowd behaviors.
For more information, you may have a look at the media overview, which give a broad overview of my work, or check the research projects below for detailed information.

In collaboration with Guy Theraulaz and Dirk Helbing, we have developed a simple cognitive model that describes how pedestrians move and how the surprising self-organization of human flows comes about.

How do we walk together?

The observation of moving pedestrian groups, such as a few friends walking together, revealed a new kind of interaction in human crowds.

In pedestrian counterflows, people walking in opposite directions spontaneously separate in two flows, which enhances the traffic flow.
Under laboratory conditions, we have investigated on the behaviour of pedestrians at the origin of this collective organization.

In ant colonies, fish schools or human crowds, patterns of collective organization are surprizingly similar.
What are the common underlying mechanisms to all these systems?
