phylogeography

My research uses DNA sequence data to elucidate the phylogeny, phylogeography, and population diversity of insects. Projects currently underway include 1) the molecular phylogeny of fruit flies (family Drosophilidae); 2) the molecular phylogeography of ladybird beetles (subfamily Epilachninae); and 3) the population genetics of East Asian eplachnine beetles.

Message

Insects are thought to be consist of about more than a half of all the species described to date. Thus, studying the evolution of insects will play an important role to understand the diversity of life on earth.
