DESCRIPTION:Speaker: Frank Juelicher\nhosted by Gasper Tkacik\nAbstract: A 
 fundamental question in Biology is to understand the morphogenetic rocesse
 s by which an organism of complex shape forms from a fertilized egg. This 
 morphogenesis involves the dynamic remodeling of tissues consisting of man
 y cells that grow and divide. The fly wing is an important model system fo
 r the study of multicellular dynamics during tissue morphogenesis. During 
 pupal stages\, the early fly wing undergoes a spectacular dynamic reorgani
 zation that involves cell flows\, cell divisions and cell shape changes. T
 his dynamic process generates the final shape of the wing. We characterize
  tissue remodeling by the contributions of specific cellular\nprocesses su
 ch as cell shape changes and cell neighbor exchanges to macroscopic shear 
 at different times. We discuss the dynamics and the mechanics of this tiss
 ue using theoretical approaches that capture the essential physics of tiss
 ue remodeling.\nOur work suggests that local tissue contraction together w
 ith anisotropic active processes drive tissue remodeling in the fly wing. 
 We show that mechanical boundary conditions play a key role in determining
  the final tissue shape.
