DSS-Retreat 2019

As in the last year we spent a couple of days (15.10.2019 till 18.10.2019) on the island Sylt to reflect our past, current, and future research work. Due to a "cold wave" we were a bit reduced this year, but anyhow, we had a very good (and producive) time on this beautiful island. Beside our research plans (reflecting the last year and planning of the next years), we also discussed teaching ...
