I joined the Prof. Helariutta’s group in SLCU as a visitor in June 2016. During my PhD research in Kyoto University with Prof. Kiyotaka Okada. I studied pattern formation in leaf development in Arabidopsis. After I finished my PhD in 2011, I joined Prof. Hidehiro Fukaki’s group in Kobe University and focused on root development, especially lateral root development. From 2016, I have been doing a research in Prof. Tatsuo Kakimoto’s group in Osaka University to study the relationship between phytohormones and cell division. This work led me to start research on cytokinin and cell division in the Helariutta group.
