Our purpose of study is to reveal how the bacterial pathogens acquire the pathogenesis and evolve through the genomic analysis. And we try to find new prophylactics and therapies for infections through the kinetic analysis in animal cell at the molecular level.

Research and Education

We mainly study about evolution of pathogenic bacteria with hybrid approach using bioinformatics and validation experiments. In addition, we study how immune system reject bacterial infection using cell lines and animal models. We have many research topics including followings: 1. Roles of microbe for human homeostasis using metagenomic data of microbiome. 2. Association study of human health and microbiome. 3. Comparative (meta) genomic analysis and experimental validation for understanding bacterial evolution and diversification. 4. Artificial mix or stimulation of indigenous bacteria for development of new medical treatment of human diseases. Anyone who have interests in our research topics is welcome. We educate students in research, reading of papers and discussion to become a principal investigator in future.
