I study evolutionary processes and species diversity mainly through mathematical modeling.

My book 'How do new species arise? - In search of the origins of biodiversity' (written in Japanese) has been published by Kyoritsu Shuppan Co., Ltd.


Gave a talk 'The phoenix hypothesis of speciation: reproductive isolation among populations experiencing extinction risk' at a symposium 'Genomics of adaptation and speciation' at The 3rd AsiaEvo conference (Singapore).

Organized a session, 'Integration over space and time' as a Discussion leader at Integration Of Speciation Research (IOS) Workshop (Tvärminne, Finland).


Published online: a theory that investigated the possibility of habitat segregation and coexistence of closely related species

Organized a session, 'Macroevolutionary patterns of diversification and implications for species persistence' as a Discussion leader at Gordon Research Seminar (Speciation 2023, Lucca, Italy). Also, presented a poster at the subsequent Gordon Research Conference.
