Functional Materials

Research content introduction

Most of living organisms use light to create biological energy and to obtain information of external world for their survival. Among them, various types of photoreceptive proteins play the central role. We especially focus on microbial rhodopsins, the photoreceptive membrane protein in micro-organisms, and aim to elucidate their functional mechanism by means of advanced spectroscopy. Furthermore, based on those insights, we are also trying the development of new molecular tools for optogenetics which is drawing broad attention in recent years.


In our research, we explore the unexploited scientific field by continuous effort and broad interest. There is a romance that unravels things that no one in the world knew.

I specialized in chemistry at university which was the most interesting when I was a high school student. I also favored living things and I wanted to study biomolecules from a physicochemical point of view using lasers for proteins of living organisms. Therefore, I chose the Photo Physical Chemistry laboratory that is doing such research at the graduate school. In our laboratory, since the experimental sample is mainly protein, it cannot be usually purchased. So, I have to make it by genetic engineering technology using E. coli and yeast on our own. We also need to make the sample to be examined by ourselves, and we have to measure it properly, both will be needed. I chose the way of researchers, because I thought that it is a very romantic job to investigate why such a chemical reaction occurs, why such a living thing is alive, the mechanism and to unravel what I do not understand. In order to understand the mechanism of biological molecules of living organisms more than anywhere in the world, I thoroughly think and proceed the research with the aim to attain the level that there is no more.
