About

Samir Raddi, DDS, Ph.D., is a French dentist-scientist and bio-entrepreneur recognized as co-founder and CEO of CEMENTIC, a deep-tech startup creating antiseptic bioceramics designed to significantly reduce root canal failures. Balancing clinical practice and innovation, he splits his time between his private practice in Paris’s 16?? arrondissement and an R&D lab at Stanford’s StartX accelerator in Palo Alto. Raddi pursued an interdisciplinary education, earning an M.Sc. in Genetics from Université Paris Descartes (2013), an M.Sc. in Tissue & Cell Biotherapies from Arts et Métiers ParisTech (2015), and his DDS from Université Paris-Descartes (2017). He completed advanced training in Periodontology & Implantology at NYU (2021) and a Ph.D. in Sciences at Université Claude-Bernard Lyon 1 (2024). His clinical training spans roles at Hôpital Bretonneau, Paris, and the University of Iowa Hospitals and Clinics, USA. While at Lyon, his research shifted toward developing controlled-release nanomaterials for endodontics, notably publishing pioneering findings in the Journal of Endodontics on chlorhexidine-loaded lipid nanoparticles embedded in bioceramic sealers. In 2018, Raddi founded CEMENTIC, directing an Anglo-French team across Paris and Silicon Valley. Their flagship product, EndoNu™, incorporates antiseptic liposomes within a calcium-silicate matrix, undergoing preclinical evaluations at StartX facilities and Paris Saclay Raddi holds multiple patents, prominently US 2020/0315923 A1, covering disinfectant bone and dental filler materials using liposomes. His startup was notably spotlighted at Paris-Saclay SPRING 50 (2025) and leverages Stanford’s extensive entrepreneurial ecosystem. Actively engaged clinically, Raddi maintains weekend clinics specializing in implants, bone grafting, alongside. He exemplifies clinician-led innovation driving advances in global oral healthcare.
