Post-doc doing research on gene therapy at the Tokyo University, previously worked on arboviral infections.
A little late this year, but I managed to get the yearly calaveras for the lab. 💀

Looking forward to two days of interesting presentations on the Tokyo University 3rd UTOPIA symposium about vaccine development. Not really my field now that I work on gene therapy but as a virologist can't stop feeling nostalgic.

Blood donation day at the hospital. I apparently accumulated some points and got a small notebook as a prize 🩸🅾️

First time using the meeting room at the top floor in my hospital. I had no idea you could see both the Tokyo Tower and the Sky tree Tower from there. 🗼

Once again, I am reminded of the importance of properly taking care of my cells. On the left, "stable" transgenic cells that express reporters after rAAV transduction, but that went three passages without selection antibiotics. On the right, the cells after reselection with high doses of G418.

A nice rainbow in Tokyo after yesterday's rain. A perfect way to begin the day.

My tiny seasonal decoration corner at the lab. 🎅
Too bad Christmas is not that big here, in the land of Origami it feels like a lost opportunity.

Cold mornings and the Ginkgo trees close to the hospital are finally turning color, at last feels like autumn 🍁

Earthquake drill at the Shirokane campus of Tokyo U. Announcements for a week and still almost didn't find my safety helmet on time
