During Georgios's undergraduate studies he moved abroad for one year and attended one semester at The University of Oulu (Finland) and a semester at The University of Umea (Sweden). He obtained his dental degree (DDS) in 2011 from Aristotle University of Thessaloniki (Greece). He first enrolled into a doctoral program at The University of Oulu in Finland, where he was involved in clinical periodontal research for a total period of four years. Georgios obtained his master's degree in clinical dentistry, with a specialisation in periodontology and dental implant biology from Aristotle University of Thessaloniki. In 2018, he was awarded with a fellowship from The Osteology Foundation to work for the Department of Periodontology at Complutense University of Madrid (Spain). In September 2020, Georgios won a second fellowship from the International Team for Implantology and moved to Graz (Austria) to work for the Department of Oral Surgery and Orthodontics at the Medical University of Graz, as a clinical tutor and research associate. He is part of the clinical team at King's College London (KCL) teaching Periodontology for undergraduate students.

Georgios was accepted into dental school in 2005. After obtaining his PhD (2015) he moved back to Greece for three years (2015 - 2018) where Georgios trained as a specialist periodontist. He has treated over 100 cases under supervision, covering the whole spectrum of non-surgical periodontal treatment, surgical periodontal treatment and dental implantology. This includes several complex cases (i. E. Vertical and horizontal guided bone regeneration procedures and sinus lifts). In Madrid he trained together with the residents of the specialisation program in periodontology and implantology. Georgios extended his stay for an additional six months in 2020, while also undertaking research pertinent to dental implantology. He obtained the status of oral surgery resident for a year, and was involved mainly in tutoring residents in oral surgery. Georgios also contributed to the ongoing research projects of the department with which he maintains an active collaboration. His research interests pertain to evidence-based medicine dentistry, periodontitis and systemic diseases, dental implantology, and peri-implantitis. Georgios has been recruited by several organisations such as The Osteology foundation, the European Federation of Periodontology and the European Association for Osseointegration to work for systematic reviews associated with consensus workshops, many of which have informed the current guidelines for periodontal and implant treatment internationally. From 2019, he has been practising periodontology and dental implantology in the United Kingdom.
