Professor Theodoros Karapantsios started his academic and research career at the School of Chemistry of AUTH, since 2001. Until now, he has supervised 14 PhD and more than 20 master theses. He has published more than 160 research papers in international scientific journals, he participated in more than 250 scientific conferences and he is the owner of 6 patents. Moreover, he has participated in more than 85 European, national, industrial and service providing research projects, coordinating more than 60 of them. Since 2020, Prof. Karapantsios is the Director of Chemical and Environmental Technology Lab in our department and an administration board member of the Research Committee and Management of ELKE AUTH, while in 2021 he was elected as the Vise President of this Committee.
He is the Greek delegate of European Space Agency Program Board, on Human Spaceflight and Exploration, since 2010. Since 2021 he is the Greek delegate of Horizon Europe project’s, “Space” administration board. In the period 2014-2019, he was the head of ESA emblematic projects, regarding drinking water and wastewater on ISS. He participated in more than 20 technology development projects and 11 parabolic flight campaigns, together with the Multiphase Dynamics research Group, that he directs. Since March 2020, he is the coordinator of AUTH wastewater epidemiology group regarding the identification of SARS-CoV-2 viral load and mutations in Thessaloniki’s sewerage.
