Professor Kunihiro Sakuma, Ph.D., currently works at the Institute for Liberal Arts in Tokyo Institute of Technology. He is a physiologist working in the field of skeletal muscle. He was awarded sports science diploma in 1995 by the University of Tsukuba and started scientific work at the Department of Physigology, Aichi Human Service Center, focusing on the molecular mechanism of congenital muscular dystrophy and normal muscle regeneration. His interest was later turned to the molecular mechanism and attenuating strategy of sarcopenia (age-related muscle atrophy). His opinion is to attenuate sarcopenia by improving autophagic defect using nutrient- and pharmaceutical-based treatments.
