Research Field

Brain is highly developed hard-wired system. Our research interest is the molecular mechanisms underlying neuronal identity, differentiation and plasticity. Our laboratory is specially working on the epigenetics, RNA-based gene regulation and the related neural functions. Our study may provide an insight into understanding of neuronal disorders caused by dys-regulation of neuronal gene expression.

Tenure-track program for junior principal investigator is just beginning to be tested in Japan academia. It would still remain to be improved in the future. However, I do believe that Japan academia would be getting more productive and attractive with higher quality of scientists and their researches than ever before, once such a fair/clear employment system is established.
