I was privileged to be at the University of Hamburg between 4/1/2012 and 6/30/212 as a Visiting Professor. Many thanks to Prof. Dr. Ulrich Gebhard for inviting me to join his research group.

Having dinner after a departmental seminar. Many thanks Prof. Dr. Arnie Dittmer and Prof. Dr. Jürgen Menthe.

We had the farewell dinner at an Italian restaurant. It is always difficult to say good by to such great colleagues.
