Giannis grew up in Ioannina. From a young age he was the "strange" child, he loved to read and learn about the human body. This led him a few years later to study at the Technical University of Ioannina in the field of Biomedical Engineering. Since 2015, he has been in charge of Human Resources and training at AIESEC in 3 different countries, while in 2018, by winning the FameLab competition, he represented Greece in the global science communication competition "FameLab". In the same year, he created TEDxMaviliSquare in Ioannina. Now with TEDx Ioannina being the largest volunteer organization in Epirus, it is also at the helm of the Ioannina Science Festival.
He speaks 2 foreign languages and firmly believes two things that science is for everyone and that there is a Santa Claus.
