Charis Katsogridakis obtained his diploma as engineer on Materials Science and Technology from the University of Ioannina. His diploma thesis was carried out in N.C.S.R. “Demokritos” under the supervision of Dr A. Nassiopoulou on the subject of electrochemical fabrication of nanoporous anodic alumina for substrate nanostructuring followed by metal assisted chemical etching of Silicon for the fabrication of silicon nanowires. Currently he is part of the Organic Electronics group under the supervison of Dr P.Argitis as PhD candidate working on the fabrication, characterization and modeling of Organic Thin Film Transistors for sensing applications. He also works on the "Nanomet" industrial project as materials engineer on novel resins for use in roll-to-roll nanoimprinting processes.
