Research Overview

In recent years, genome information of various species has been mapped, and genome science is developing with the use of that information.
To make clear the evolutionary process of living organisms and to understand how biological diversity is preserved, it is absolutely necessary to make clear the diff erences in diff ering species and within the same species at a genome-sequence level. I am aiming to shed light on how variations emerge at the DNA level, how those variations are preserved and become fixed, and, in particular, the effect that chromosome structure has on DNA variation.
Currently, my research is focused mainly on using plants to analyze the evolutionary process of centromere functional regions, variation patterns in genetic locus that are epigenetically regulated, and also to analyze intra/interspecies variation patterns of transposable elements.
