2023/04/01 - Senior Research Scientist


Hi, what’s up! I’m Ryosuke (Ryo) Iritani. I’m originally from Kobe and did my biology and math undergrad at Kyoto University in Japan. I started my Ph.D. with Yoh Iwasa at Kyushu University in 2011 and worked as a research fellow (DC1) from 2013, visiting Lausanne (Switzerland) and Montpellier (France) to improve my theoretical skills. I then received Ph.D. in 2016 and started my postdoc at the University of California, Berkeley (as a fellow at the University of Exeter, the UK).

I am broadly interested in the field of evolutionary ecology, with a special focus on evolutionary game theory in structured populations. I’m very keen on applying mathematics to biology. Of my recent (2020), particular interest is information theory, so that we can describe natural selection.

I like coffee, soccer, typographical fonts, cooking, math, and living organisms (with a special passion for insects).
