Title:Active reorganisation of tissues: Phase transition of ideas from physics to biology
Abstract: Multicellular organisms are emergent thanks to patterns formed at multiple scales. These patterns are interconnected, and can also emerge due to patterns at smaller scales. In this talk, the patterns formed due to neighbour exchange of cells in dense tissues would be presented. These patterns are essential during embryogenesis(development of an organism from a fertilized egg), wound healing and diseases like cancer. The study of these patterns lie at intersection of active matter, turbulence, elasticity, plasticity, and physics of foams. It is everything, everywhere, all at once.

Title:What causes creep bursts in the Åknes landslide, Norway?
Abstract: Slow creeping landslides move at rates of millimeters to several meters per year. They can progressively weaken over time by rock mass damage processes that may occur by constant slow slip or sudden transient slips. These transient slip events, also called creep bursts, may induce short-term loading and hence can control landslide stability. Here, I present extensive multiphysics data series of the Åknes landslide, Norway. This landslide is moving at a slow rate of 6 cm per year, and could generate a large tsunami wave in a fjord if it would rupture catastrophically. I detected creep bursts in this landslide and built a catalogue of these events. Creep bursts interact with a distinct steady creep trend related to seasonal variations of precipitations. I analyze the creep bursts in regards to micro earthquake activity and water pressure levels, to study their origin and discuss possible mechanisms of formation.
