Research Subjects:
    Our research aims to decipher evolutionary information retained in genomic DNA sequences in order to understand the history of biological evolution in a geological time scale. There have been a variety of organisms living in a variety of environments on earth. They all have made their unique evolutionary history tightly linked to changes in local environments. Such history relates to broad aspects of the phylogeny, biogeography, bio-geo interaction, and evolutionary correlation between molecules and phenotypes. 
    We are especially interested in reconstructing the evolutionary history of vertebrates such as reptiles and fishes. We primarily use molecular phylogenetic approaches to establish reliable phylogenetic frameworks with which to interpret independent evolutionary information based on morphological characters and/or fossils. Molecular phylogeny has revolutionarized evolutionary biology and it will continue to enrich our evolutionary understandings. 
    Mitochondrial genomes provide very useful information source for this purpose due to a number of reasons including less frequent DNA recombination and gene duplication/deletion. We have been characterizing molecular evolution of mitochondrial genomes and genes of various vertebrates. However, it is also within our scope to decipher evolutionary information from nuclear genomes using new techniques, such as the next generation sequencing.
