Conference Program

The conference program and the book of abstracts can be downloaded as a PDF below...

Extended Abstracts: If an extended abstract is available you can find it as a PDF below. The IDs correspond to the IDs mentioned in the book of abstracts.

You may notice discrepancies between the online program (depicted here, PDF download) and the book of abstracts or the list of talks and posters below. These came about due to last-minute changes and we might even have to shift some items during the week. We will post updates here, if necessary.
