Research Summary

Our group aims to infer the molecular-level history of complex life, based on molecular phylogenetic approaches to evolutionarily dissecting biodiversity with increasing knowledge of cellular events from genome-wide profiling. We mainly focus on vertebrates including elusive wild species with unique phenotypes. Our interests are categorized into these themes.

1) Elucidating the evolutionary history of genomes by cross-species comparisons
2) Decoding genome evolution mechanisms taking cellular events into account
3) Improving genome-wide data acquisition and analysis methods

The FoxG group of genes analyzed as a proxy of the whole genome. These genes have different retention patterns (A), evolutionary rates of the genes and flanking genomic regions (B and C, respectively), and embryonic expression domains (D, in catshark embryos). Their inter-relationship and its orchestration within a genome remain largely unexplored. Our group tackles this sort of questions across different genes, biological processes, and animal lineages, to bridge a gap between genotypic and phenotypic evolution.
