Professor Kunihiro Sakuma is a Physiologist working in the field of skeletal muscle at the Tokyo Institute of Technology in Japan. He began his scientific career in the Department of Physiology, Aichi Human Science Center, focusing on the molecular mechanism of congenital muscular dystrophy and normal muscle regeneration. His interest later turned to the molecular mechanism and the attenuating strategy of sarcopenia (age-related muscle atrophy). Preventing sarcopenia is critical for maintaining a high quality of life in the aged population.
