Scientific Advisory Board

The Scientific Advisory Board of ESCI is composed of recognized professionals and experts in the medical-scientific field of ceramic implantology. It advises the ESCI board and stands in its competent occupation for the scientific and international orientation of the ESCI. The Advisory Council meets at least once a year as the “European Council for Ceramic Implantology” and sees itself as an independent panel of experts – any external influence on the body’s decision-making is excluded.

Tasks of theSscientific Advisory Board:

  1. Comment on the technical and scientific performance of ESCI on a regular basis,
  2. participate in the development of medium and long-term goals in an advisory capacity,
  3. promote collaboration with other partners,
  4. to provide advice in the technical and scientific field,
  5. give expert advice to ESCI partners on request.

The members of the Scientific Advisory Board are appointed by the President of the ESCI with the unanimous approval of the Board for a four-year term of office.

Born in 1970, Jérôme Chevalier is currently full Professor at the National Institute of Applied Sciences, in France. After receiving his phD in 1996 (Mechanical properties of biomedical grade zirconia), Jérôme Chevalier first became Ceramic Engineer in Saint Gobain Group, responsible for the R&D activity on biomedical applications of ceramics. In 1997, he joined the National Institute of Applied Sciences, in Villeurbanne, as assistant Professor, then full Professor in 2004. He is currently Director of Materials Science Laboratory MATEIS (180 persons). His research activity is focused on ceramics, from their processing to their mechanical and functional properties. He has published more than 180 international papers with a review process, 7 review papers in journals and encyclopedia, 3 book chapters. He is co-author of 10 patents and his research has led to the commercialization of 6 medical products. More than 8000 papers have cited his work according to Google Scholar. 45 of his papers have been cited more than 45 times (h factor equal to 45). Jérôme Chevalier has been member of the ‘Institut Universitaire de France’ from 2009 to 2014, and he is editor of the Journal of the European Ceramic Society, leading journal (IF 2.9) on ceramics and of the open access journal ‘Materials’ (IF of 2.8). He is highly recognized for his work on the mechanical and fatigue behavior of ceramics, on the aging process in zirconia based ceramics and composites, and more generally on bioceramics (ceramics for orthopedic implants, scaffolds for tissue engineering and dental ceramics). He has participated to a large number of European projects on that topic, including a recent coordination (LONGLIFE, FP7 2012-2016). He was recently awarded by the CNRS with the prestigious ‘Innovation Medal’ and by the French Society of Materials with the ‘Sainte Claire Deville’ medal.
