Deputy Director of RIKEN Center for Sustainable Resource Science
Group Director of Chemical Biology Research Group

I wonder why microorganisms produce various compounds with chemical and biological diversities. To resolve the mystery, I am interested in biosynthesis gene clusters of microorganisms. In addition, I want to contribute to the society through the chemical biology research with bioprobes and the molecular target therapy of tumors.
