A better understanding of the mechanisms behind cell motility is crucial to controlling pathologies (e.g. cancer) and for understanding embryonic development. However, most of our knowledge of cell migration stems from in vitro motility assays of limited physiological relevance. In this project we exploit the embryonic migration of Drosophila macrophages as an in vivo motility system as these cells can be imaged live during development at an unprecedented spatio-temporal resolution in vivo. We will combine the genetic tractability of this system, computer vision techniques, and computational models to examine the biophysics of migrating cells within this in vivo context.
