Nice workshop in Cambridge

I co-organized a workshop in March 2023 at the Isaac Newton Institute in Cambridge: https://www.newton.ac.uk/event/rntw02/ It was so nice to see many colleagues after a long break! Instead of a regular scientific talk, I gave a presentation by title “Science Showmanship”. It contained some scientific stand-up comedy and stories about being a mathematical YouTuber. In

Joining the Board of Finnish Nuclear Society

The Finnish Nuclear Society elected me to represent University of Helsinki in the Board of 2023. I am really excited about this position at the time of the world’s first geological disposal (in Finland!) of spent fuel and the rise of small modular reactors (SMRs). Nuclear energy plays a significant role in the transition away
