Research Description

The remarkable economic development and population growth in recent years might threaten the food shortage on a global scale. I have researched on reproductive physiology and aim to contribute to the development of efficient food production. Notably I am tackling a big issue in animal science, mastitis, so-called occupational disease of dairy cattle. The mastitis usually caused by a bacterial infection is the most prevalent disease and the greatest source of lost revenue, about hundreds milloin dollar annually in Japan. In my previous work, mice milk contains L-amino acid oxidase (LAO), a enzyme decomposes particular free amino acid and generates hydrogen peroxide. LAO-knockout mice exhibited weak resistance to an intramammary bacterial infection. In dairy cattle, the expression level of LAO seems quite small compared to mice. I believe if we can enhance the LAO expression endogenously, it will enable the generation of mastitis resistance cow.

About TUAT's tenure-track program

This program is nice for young scientists. To keep it on TUAT and Japan, We will also need to be nice scientist. I hope this program would be more improved consistently for next generation.

Future aspirations

I would like to always keep double standard in my mind; one is going the basic research for battle with other researchers and survive in the scientific world, another is doing applied research based on practical science to resolve facing problems in veterinary, animal science and other fields. I know it is hard task, but I would do and finally make an attractive laboratory.
