Thimios Mitsiadis is a Professor of Oral Biology in the Medical Faculty at the University of Zurich, Switzerland. He conducts research in the fields of stem cells, genetics, molecular and experimental biology related to orofacial developmental and regeneration processes. Thimios Mitsiadis obtained a DDS degree from the Dental Faculty of the Kapodistrion University of Athens (Greece), a Master's degree for Immunology, Genetics and Differentiation and the Ph.D. in Developmental Biology from the University of Lyon (France). He conducted postdoctoral studies at the University of Helsinki (Finland), Karolinksa Nobel Institute (Stockholm, Sweden) and Yale University (USA). Thimios Mitsiadis was a Professor at the Mediterranean University (Marseilles, France), Visiting Professor at the Ecole Normale Superieure of Lyon (France), Clinical Senior Lecturer at King's College London (UK) and Associate Professor at the Dental School in Athens (Greece). From 2006 to 2010, he was director of the Institute of Oral Biology at the University of Zurich (Switzerland). Since 2021 is also affiliated to the Technological Research Institute of Crete, Greece. For more than 30 years, Professor Mitsiadis has been studying the molecular basis and interactions involved in tooth development, pathology and regeneration. A major milestone in his previous research was the creation of teeth in chick embryos after the transplantation of mouse neural crest cells.
