Athanassios Philippopoulos is currently working as an Associate Professor in Inorganic Chemistry at the NKUA (Department of Chemistry, Athens Greece). After his PhD thesis in the field of organometallic chemistry with Prof. N. Hadjiliadis at the University of Ioannina, he joined the group of A.C. Filippou, at The Humboldt University of Berlin and then attended the University of Bonn, working in the fascinating area of transition metal complexes that display triple bonds to a heavier analogue of the 14 groups (i.e., Ge, Sn and Pb). When he returned to Greece, he decided to move to the area of third-generation photovoltaic solar cells, also known as dye-sensitized solar cells. Since 2006, he has been working in the Chemistry Department of the NKUA. His research interests focus on the design, synthesis and characterization of new molecular materials with specific properties (synthetic coordination, organometallic chemistry) and applications in (i) energy conversion (dye-sensitized solar cells), (ii) bio-inorganic chemistry/metal-based drugs, and (iii) homogeneous catalysis (transfer hydrogenation, etc.)
