The aim of the colloquium is to bring together researchers with interests in vortex dynamics (classical and quantum) and related topics such as mixing and geophysical fluid dynamics, to allow both communication of new results and ideas, but also cross-fertilization between linked subjects. The topics to be highlighted include:

• Vortex dynamics: interaction and motion of vortices.
• Vortex stability, linear and nonlinear.
• Mixing of vorticity and scalars induced by vortices.
• Role of vortices in geophysical fluid dynamical problems.
• Vortex dynamics and stability in superfluid helium and atomic Bose-Einstein condensates.
• Superfluid turbulence.

The colloquium runs from Tuesday morning (11th September) through to Friday lunchtime (14th September). There will be 8 invited lectures of length 50-60 minutes, contributed papers of 20-30 minutes and posters.

Invited speakers: David Dritschel (University of St. Andrews, UK), Stephane Le Dizes (Universites d'Aix-Marseille I/II, France), Tony Leonard (Caltech, USA), Tomasz Lipniacki (Institute of Fundamental Technological Research, Poland), Koji Ohkitani (University of Sheffield), Ladislav Skrbek (Charles University, Czech Republic), and Makoto Tsubota (Osaka City University, Japan).
