In ecology, we have a term called “niche”. The word originally refers to a depression made in a wall to hold ornaments or plants, but in ecology it is defined as the range of environments in which individuals of a species can survive, grow, and reproduce. There are various environments on earth, but most species cannot survive in all environments. Only those who can secure their niche will survive.
“Niche” has become a term used in general society, such as a “niche industry”. However, when “niche” is used in general society, I feel that it has the nuance of “narrow space”. “Niche” as used in ecology does not necessarily have such nuances. Some organisms have wide niches and are called “generalists”. Species that have only a narrow niche are called “specialists”.
Our Graduate School of Life Sciences aims to be a generalist in the life sciences. By bringing together researchers (specialists) from a wide range of hierarchies, from molecules to ecosystems, we cover all areas of life science. Not only do our individual researchers aim to be on the cutting-edge, but we also aim to create new research areas through collaboration by researchers from different hierarchies. We are pioneering a new niche that other research institutions cannot occupy.
In 2024, Tohoku University was certified as a University for International Research Excellence. The mission of Tohoku University is to contribute to the realization of a peaceful and just human society through world-class research, cultivate a talented workforce, collaborate with diverse partners in society, and embark on a variety of changes and challenges. Our Graduate School of Life Sciences has also started working on hiring cutting-edge researchers, providing new international education, and improving research facilities. We would like to continue to evolve with the aim of producing even more impactful research results and nurturing students who will contribute to society.
