Pierre Weiss, PhD, DDS, received his dental doctorate in 1989. He received his Master of Science in biomaterial (Nantes) in 1993 and his PhD in biomaterial (Nantes) in 1997. He is a professor in biomaterials at the University of Nantes in the dental surgery department and the hospital. He was the head of the INSERM/Nantes University Unit 791, Centre for Osteoarticular and Dental Tissue Engineering, National Institute for Health and Medical Research (INSERM), UMRS 791LIOAD. Now he is Head of the REGOS Team in the UMRS 1229 RMeS Unit. His research interests include the chemistry and characterization of macromolecular solution and hydrogels to prepare synthetic extracellular matrices for tissue engineering of cartilage and bone. He has two main fields of research in biomaterials: The first concerns injectable bone substitutes, e.g. suspension of calcium phosphate ceramics or calcium phosphate cements. He also develops self-crosslinking hydrogels of polysaccharides for tissue engineering and drug delivery systems. He has also managed clinical research in odontology. He is a nominated Fellow of Biomaterials Science and Engineering (FBSE) for the World Congress of Biomaterials, WBC 2020 (WBC members who gained excellent professional standing and high achievements in the field of biomaterials science and engineering). About 200 ISI indexed publications, more than 200 communications, 50 invited lectures, 7 patents and Hirsh index: 50, 6200 citations. Researcher ID: AAE-9260-2020
