Dr. Kadomatsu started his career in basic medical research after being a physician of pediatric neuroblastoma. During his graduate studies, he discovered the glycan-binding growth factor midkine. He has been researching the involvement of cancer, neurology, and inflammation. For this achievement, he received the Young Investigator Award from the Japanese Biochemical Society in 1997.
His research with a Chinese graduate student led him to become particularly interested in the relationship between glycans and the nervous system, which has become the focus of his research. He was a representative of "Neuroglycobiology" (2011-2015), the Grant-in-Aid for Scientific Research on Innovative Areas by the Ministry of Education, Culture, Sports, Science and Technology of Japan (MEXT). He currently represents the "Human Glycome Project," Roadmap 2020, MEXT.
He served as the President of the Japanese Society of Carbohydrate Research, Editor-in-Chief of the Journal of Biochemistry, and representative of the Asia/Australia/Africa region of the Advance in Neuroblastoma Research Association. He holds an honorary professorship from the Chinese University of Hong Kong.
