The mission of the Department of Biology in the Graduate School of Kyung Hee University is to replace mysteries in the living world with understanding. Every piece of discovery and understanding of life leads us to a new world of development in which the sum of our efforts provides the fundamentals of human well-being via diverse humane technologies. The department provides a curriculum at the leading edge to support first-rate graduate students at all levels. There are five majors in the department: Botany, Animal Biology, Microbiology, Molecular Biology, and Environmental Biology. Directors of fourteen research laboratories in the department have actively participated in many national and public research projects. Recently, the department developed a road map to establish the most competitive and specialized research consortium in the area of biomedical sciences. We are about to establish new traditions in biomedical sciences including neuroscience, oncology, and microbial infections. The department also has gained nation-wide recognition in animal ecology and ornithology.
