Those of you who have not registered should do so by clicking the Registration Link. This will also give you information on the Royal Society. There is no registration fee. If you have not preregistered, please do so using the Pre-registration Form.

The RSDM on the 16th and 17th will be at the Royal Society whose map you will find at the Registration Link. The satellite meeting on the 18th will be at Remax House of the University College London. More information on the location of Remax House will be given later.

We encourage you to present posters which will stay during the Discussion Meeting. Applicants to the poster session should send title and abstract (on one page, in PDF format) to us by December 15.

There will be a banquet for all attendees in the evening of the 17th at the The Jeremy Bentham Room (formally the Upper Refectory) of University College London. The dinner is 27.50 British pounds per person. Please let us know if you (and your guest) wish to attend.

There is no fixed accommodation for this meeting unless you have been notified by the Royal Society. Information on accommodations in London is on the Royal Society website which you can find via the Registration Link. You may choose to reserve your hotel yourself.

We look forward to an inspiring Meeting!!
