This working group is aimed at developing a long term science vision for optical interferometry in the ELT and ALMA deployment era. Firstly, the bounding characteristics of the second generation array will be defined, then given the more complex nature of this group when compared to those above we plan to run two meetings the first one to decide the top level science cases and the second one presenting detailed science cases.

The working groups is managed by Andreas Quirrenbach (chair), Guy Perrin (co-chair) and  Jean Surdej (deputy).

In JENAM 2010 a Symposium on this topic will be organized. Further information is available. Deadline for submitting abstracts is the 30th June.

During OPTICON/FP6 two workshops took place in Liège relevant for this working group:

• 2004 Science Case for Next Generation Optical/Infrared Interferometric Facilities (the post VLTI era)
• 2005 Technology Roadmap for Future Interferometric Facilities
