SUMMARY:Interacting Active Matter
DESCRIPTION:Active Matter Seminar\n\n\nSpeaker: Amin Doostmohammadi\, Niels Bohr Institute\, University of Copenhagen \nTitle: Interacting Active Matter \nAbstract: I will focus on the interaction between different active matter systems. In particular\, I will describe recent experimental and modeling results that reveal how interaction forces between adhesive cells generate activity in the cell layer and lead to a potentially new mode of phase segregation. I will then discuss mechanics of how cells use finger-like protrusions\, known as filopodia\, to interact with their surrounding medium. First\, I will present experimental and theoretical results of active mirror-symmetry breaking in subcellular skeleton of filopodia that allows for rotation\, helicity\, and buckling of these cellular fingers in a wide variety of cells ranging from epithelial\, mesenchymal\, cancerous and stem cells. I will then describe in-vivo experiments together with theoretical modeling showing how during embryo development specialized active cells probe and modify other cell layers and integrate within an active epithelium.
