Abstract
A very common phenomenon in biology and ecology is the collective movement of individuals, whether these be birds, fish, cells, etc. This leads to the general question: What are the hallmarks of collective movement?

In this talk, I will review an interdisciplinary study we have been carrying out over the past decade on a powerful model paradigm for collective cell migration, namely, the chick cranial neural crest. I will show how a relatively simple multiscale hybrid cellular automaton model, combined with experimental studies, can lead to new insights into the phenomenon of collective cell migration.
