Being able to conduct my experiments at Riken was a great experience. The technical know-how of the lab members helped me tremendously with setting up my experiment, and I was able to take parts of the set-up with me to my new lab. Everyone in the lab was very supportive. Administratively, everything went smoothly and without any problem, and whenever I had a problem it was easy to find someone who would help me. The only that was lacking for me was informal opportunities to discuss the content of my research, since most lab members were focusing on their own projects without allowing much time to discuss each other’s work outside of the formal lab meeting contexts. I will definitely continue collaborating with my host on this project. After a few years in Europe and/or the USA, it is also a possibility to return to my host lab in Japan for another project. We have discussed this possibility before I left and will take it up again in a few years.
