Being a relatively small sized team, I like to think of my ‘PhD kids’ as members of different generations. When I moved to Luxembourg, and after a small year of integration in the new environment, my first generation with François, Guido, Bogdan and Giorgos (who was maybe the only representative of a generation 1.5) built the foundations of the MobiLab Transport Research Group and created the links and the friendship atmosphere we can still enjoy in the team. The generation with Giulio, Xavier and Ariane has just concluded this second chapter. I am happy to say that even if this was a more complicated cohort (Covid reducing our interactions, troubles with sponsoring companies, some difficulties due to new and very different research topics and modelling approaches), it was also memorable! Congratulations Dr. Giorgione, Dr. Mazur and Dr. Scheffer! Ad Maiora!
