I love outdoor activities: hiking, skiing, fishing, and collecting wild plants for eating TEMPRA.

経歴 I received a Ph.D. degree from Graduate School of Agricultural and Life Sciences, The University of Tokyo. After working as a special postdoctoral researcher at RIKEN for two years, I was appointed an assistant professor at Tohoku University.

The genes for PCB degradation are located on a mobile genetic element, and its intercellular transposition was demonstrated first among related elements. I have also been conducting research that aims to understand the catabolite control mechanisms of a soil bacterium that degrades PCBs, which are man-made persistent substances. While conducting such so-called “wet research,” I have been creating and publishing computer software that allows efficient analysis of genomic data. A software program designated “GenomeMatcher” enables comparative genomics as well as information processing for a wide variety of purposes. “AceFileViewer” and “GenoFinisher” support finishing of microbial genomic sequencing, while “ShortReadManager” is useful for processing a huge amount of data generated by next-generation sequencers.
