DESCRIPTION:Speaker: Lisa Manning\nhosted by Carl Goodrich\nAbstract: Multi
 cellular organisms generate complex morphologies required for their functi
 on. Organisms control these morphologies by tuning active forces\, and als
 o by altering the emergent “material properties” of a tissue\, i.e. th
 e rheology of the tissue. In many cases\, organisms take advantage of dram
 atic changes in the rheology that occur when the material undergoes a rigi
 dity transition from a fluid-like or floppy state to a solid-like or rigid
  state\, which in turn depends on internal parameters at the scale of cell
 s and molecules.  I will discuss recent work to understand the mechanisms
  that organisms use to control such transitions\; some tissues alter their
  rheology via a first-order rigidity transition controlled by connectivity
 \, while others utilize second-order rigidity controlled instead by the lo
 cal cell or fiber geometry.  Inspired by this second class of biological 
 examples\, I will also discuss some new approaches we have developed to de
 sign multifunctional mechanical metamaterials that can tune their rigidity
  while optimizing other desired properties
