The Department of Biology was founded with three laboratories in 1949. Two of them were protein chemistry (Professors Akabori and Okunuki) and one for cell biology (Professor Kamiya). The department was different from ordinary biology, zoology and/or botany departments, which are common in the other university at that time. We follow this unique tradition in a modernized way and are always aiming at developing new research areas in biology. We emphasize interdisciplinary research and education by constructing a network based on the study of bio-molecules. We offer small size exercise classes and honoring experimental courses in early undergraduate stages. Undergraduate students join laboratory works at many different biological fields, such as single-molecule biology, protein structure and function, DNA replication, plant and animal development, neural circuit network and theoretical biology to elucidate the life and living organisms.
