Osamu Suzuki is Professor and Chair of Division of Craniofacial Function Engineering, Tohoku University Graduate School of Dentistry, Sendai, Japan since 2004. The division is in charge of education and research in the field of biomaterials science and skeletal tissue engineering. He was Researcher in Japan Fine Ceramics Co. Ltd., Sendai, and Senior Researcher in JGC Corp., Yokohama/Oarai, Japan from 1986 to 2004. He found in the first place an osteoconductivity of synthetic octacalcium phosphate (OCP) in comparison with other calcium phosphate materials, such as non-sintered hydroxyapatite, in his PhD study, carried out until 1991, in Tohoku University Graduate School of Medicine, Sendai, Japan. He has also been developing OCP bone substitute materials, combined with natural polymers, such as collagen, gelatin, alginate and hyaluronic acid, together with his collaborators since 2004. He received his MSc degree in Yamagata University Graduate School of Engineering, Yonezawa, Japan on strength design of bioceramic materials at 1986. He joined a visiting scientist program in Forsyth Dental Center, Physical Chemistry Department, Boston, USA from 1992 to 1994 to study the synthesis and the physicochemical properties in OCP and its related calcium phosphate materials. He has also been focusing on the study to elucidate the mechanism on how OCP materials property relates to activating bone regeneration associated with the cellular function involved in the bone repair by OCP. He received the Award of Japanese Society for Biomaterials (JSB) in 2015 by a series of studies “Elucidation of osteoconductivity and establishment of biomaterial science of OCP bone substitute materials.? He is an Executive Committee Members of the JSB and the Japanese Society for Dental Materials and Devices (JSDMD), respectively, and Editor-in-Chief of Dental Materials Journal since 2018.
