PUBLICATIONS

This page collects relevant publications of the consortium, listed according to the respective project. If publications contribute to more than one project, they are listed only once. What is particularly pleasing is the relatively large number of joint-node publications involving more than one PI at a time. Also, a number of high profile publications have been put out, including 14 papers in the Nature and Science groups until now.
