The future of interferometry in Europe in the next decade will be addressed  in the context of other European and worldwide ground infrastructures such as  ALMA, E-ELT/TMT and SKA and space infrastructures such as the GAIA satellite  as well as emerging optical interferometers in the USA such as the Large  Binocular Telescope Interferometer, and the NPOI, CHARA and MROI arrays. This  working group involves major players in optical interferometry as well as members  from the community at large. This new working group builds on the scientific  reports delivered by the previous working groups focused on circumstellar disks  and planets and on the galactic centre and extragalactic science. 

The working group is lead by Jorg-Uwe Pott (chair),  Jean Surdej (co-chair).
