Academic Career
I received a PhD in 1998 from the Department of Chemistry, School of Science, the University of Tokyo, under the supervisor of Professor Yoshio Umezawa. After spending five years as an Assistant Professor, I started an independent position as an Associate Professor at the Institute for Molecular Science (IMS), Japan, since 2005. While at the University of Tokyo and the IMS, he contributed to the development of fluorescence and bioluminescence imaging probes and their application in live cells. In 2007, I joined again the Department of Chemistry, School of Science at the University of Tokyo, as a full professor.

Why My Lab?
Our lab is comprised of a multi-disciplinary team of scientists who specialize in analytical chemistry, molecular imaging, protein engineering, medicinal chemistry, physical chemistry, chemical biology and basic biology. We are exploring new optical methods to deepen understanding of biological systems and to break new ground in applications to the world of life. For this objective, our laboratory is investigating methods for optical imaging, chemical library screening, cDNA library screening, and optogenetic modules to control enzymatic activities in complex biological systems of interest.
