I am a researcher working for the Japan Atomic Energy Agency (JAEA) within Masahiko Machida’s group in the Centre for Computational Science & e-Systems. I am based in Kashiwa, Japan.

My research is on the radioactive contamination released by the Fukushima Daiichi nuclear accident.

My background is in nuclear safety analysis, mainly for decommissioning projects in the UK. My PhD was in the physics of glass and colloidal suspensions at the University of Bristol.
