Waves, Coherent Structures, and Turbulence


The workshop will bring together physicists and applied mathematicians researching in the area of waves, coherent structures and turbulence. The even has four sessions corresponding to the following themes:

  • Classical vortex dynamics
  • Nonlinear waves
  • Wave interactions and turbulence
  • Coherent structures and topological excitations

Each session will have an introductory lecture on the theme (aimed at the non-experts) and then a handful of more specific talks. The participation of PhD students, postdocs and early career researchers to the event is particularly encouraged. Depending on the numbers of participants, a formal poster session might also take place.

The local website for the meeting can be found at
