Study for molecular evolution using genome sequence and gene expression

Faculty

Research Summary

We study the evolutionary process for acquisition of novel phenotypic characters by comparative genomics and molecular evolutionary approaches, using various materials such as animals, fungi, or bacteria. Particularly, we have recently focused more on (1) Molecular evolutionary analysis of genes associated with sensory organs, (2) Biodiversity and dynamics of marine microbes based on metagenomic analysis, (3) Molecular phylogeny based on mitochondrial and nuclear genes, (4) Study of disease causal gene and gene model of disease, (5) Knowledge finding and system development for big data in life science.
