The other day, my friend Christine asked me. "Can you be an international assessor of PhD thesis written by Helle who is my PhD student?" Me? are you serious? you might find more sutable person than me... However, the thesis is about pediatric drug development which is one of our lab research topics, and Christine is my good friend, so I decided to accept the work. Everything was new for me because I've nvere assessed foriegn PhD thesis although I've read several foriegn PhD theses, theses in KU Leuven. It seemed resembling to Belgium way, but different, I guess. Anyway, they invited me. This season in Copenhagen was woderful with nice cool weather compare to Japan, longer day light with bright sun shine sometimes. I was so nervous but other assessors, Mrieke and Christine helped me a lot that made me OK. The defense went very well. Helle answered my odd questions that was satisfactly. In the end, we concluded her thesis was good enough for PhD. So she got PhD degree....
