Thank you for the invitation to the New Years Reception of the Federal President of Germany and Mrs Büdenbender, 10 January 2019 in the castle Bellevue, Berlin! 
[8 Jan 2019] 

Since January 2019, I am an editor of Analysis Mathematica for the area functional analysis, operator algebras and quantum groups. Submissions welcome! 
[13 Nov 2018] 
The mobility support for the project Quantum groups and quantum probability has been approved by the DAAD/Procope for 20192020  Thank you very much! 
[5 Mar 2018] 

Alexander Mang receives an award (8 week stay at the Max Planck Institute for Mathematics in Bonn) at the students conference of the DMV (German Mathematical Society), 45 March 2018 in Paderborn for his talk on his Bachelor's thesis Neutral pair partition categories, written under my supervision. 
[13 Mar 2017]  I am very happy having received the Landespreis Hochschullehre 2016 (federal state teaching award) awarded by the first minister of Saarland for the preparatory math courses for refugees for studies in MINTsubjects!
