Dear Kareem, A warm thanks again for the kind invitation, the perfect organisation (yes, don’t be shy!) and the nice moments spent during this hearty scientific event. I deeply enjoyed to join and to share some views with many colleagues. As discussed you find attached my receipts for my travel & stay expenses in Berlin. These are essentially my train tickets, my hotel bill and a 3-day pass for the subway that you find attached. Please pay attention that the train tickets are in Swiss Francs (CHF), and 246CHF = 264€. I also attach my bank details, and let me know if you need other pieces of information. All the best, kind regards, Luc [Image]<https://www.epfl.ch/> Prof. Luc THÉVENAZ Emeritus EPFL, STI-DO PH-STI Station 11 1015 Lausanne, Switzerland Follow us on social networks: Tel.: +41 (0)21 69 3 47 74 luc.thevenaz@epfl.ch <mailto:luc.thevenaz@epfl.ch> Personal homepage<https://people.epfl.ch/luc.thevenaz> [Image]<https://twitter.com/EPFL>[Image]<https://www.facebook.com/epflcampus>[Image]<https://www.linkedin.com/school/epfl>[Image]<https://www.instagram.com/epflcampus>[Image]<https://www.youtube.com/user/epflnews> Wikipedia<https://en.wikipedia.org/wiki/Luc_Th%C3%A9venaz> Group homepage<https://gfo.epfl.ch/>
