Bioscience and Biotechnology

At our Department of Bioscience and Chemistry, the leading edge of education and research is being done with “bioscience and biotechnology” as common keywords. The research fields of the department are immensely multiplex. Our biggest aim is to solve the basic issues which are quite important to human existence, such as food, health, resources/energy and environment, through performing basic researches regarding to expression mechanism of life phenomena which living things as plants, vertebrates and microorganisms show.

Our mission is to foster human resources of bioscience via biotechnology etc., at the same time to contribute to improvement of human quality of life, by choosing from genes to earth’s ecosystems as subject of study.

Check!

  • Department of Bioscience and Chemistry is comprised of following 10 fields.

  • Utilizing technique of “chemistry”, the world of interdisciplinary integrated science extends, which thoroughly explores soil, food, vertebrates and microorganisms.

  • The four themes “food”, “health”, “energy” and “environment” are binding each laboratory in a mosaic states, networking inside the whole department is lively.

  • Joint researches between enterprises are also very active.
