We research behavior, ecology and evolution mainly using insects. Research topics are the evolutionary process from the view point of natural selection and/or sexual selection, environmental effects on traits in animals, life-history evolution, and applied entomology in evolutionary biology.

Main research topics
Sexual selection and sexual conflict
How do female insects choose mates? Why are the sexes in conflict in some insects? We research the mechanism of the process of sexual relationships.
