Research Description

It has been revealed that the diet is not only energy source, but also a variety of biological functions. In particular, the intestinal tract is a very interesting organ which is called “inner but outside world”. In addition, gut microbiota coexist in the host intestinal tract, and recent studies have suggested that the composition of gut microbiota is closely related to our health. It is well-known that the diet affect the composition of gut microbiota, and as a result, gut microbial metabolites derived from diet are expected to act the intestinal tract and peripheral organs via the blood. In our laboratory, in order to clarify the novel functional foods, we will focus on the investigation of interaction between diet and gut microbiota for our health.

About TUAT's tenure-track program

TUAT tenure track program provides the enough time, environment, and start-up budget for our research. In addition, the educational duty is reduced during the program. We are able to receive the supports and advices on research and education from mentors and other professors. This program is a great chance for young researchers as principal investigator.

Future aspirations

I really appreciate the people who have supported for being able to establish my laboratory. During 5 years (tenure track period), I would like to contribute to the development of research even a little.
