GREGOR Meeting 2018

The GREGOR meeting 2018 will take place on December 13 and 14 at the Musikakademie in Staufen (near Freiburg).



The registration is closed. If you would like to attend and forgot to register, send me an email. If you would like to give a presentation, please send its title (and an abstract/explanation if necessary) via email to Lucia Kleint (


The registration deadline has passed (September 10, 2018) and the rooms at the Akademie were booked. The accommodation is single rooms directly in the Akademie, which have their own bathroom (without toiletries) and cost 46 Euro for 1 night, or 73 Euro for 2 nights. You can arrive either on the 12th or on the 13th, but we will need to vacate all rooms on the 14th. Only people whose registration fee arrives until September 11 will have a room guaranteed at the Akademie. Please be aware that Staufen is a small place with very limited lodging, so your only other option may be to commute from Freiburg. Please also be aware that if you book a room at the Akademie by indicating it in the doodle and cancel later, you will be liable for the cancellation fee, which is 10 Euro per room 12-6 weeks before the meeting and the full cost if canceling within less than 6 weeks before the meeting.


If you have not paid the fee (this includes members of KIS), please do so as soon as possible. The registration fee is 75 Euros, payable to KIS and contains lunch (3 courses), drinks, and coffee breaks on both days. Please pay via bank transfer:
