Dr. Ioannis Raptis received his BS degree in Physics (1989) and his Ph.D. on e-beam lithography (1996) from Physics Dept. University of Athens. The experimental part of his Ph.D. thesis was carried out at IESS-CNR (Rome, Italy). The software part of his thesis became commercial product of Sigma-C GmbH. From 06/2003 he works at the IMEL as researcher and from 03/2006 as senior researcher on the implementation of technologies and electronic/photonic devices in the micro/nano scale for bio(chem) sensing applications. He is/was Key Researcher and Coordinator for several national (GSRT) and EU (FP6, FP7) funded research projects in the areas of nanotechnology and microsystems. He is program and steering committee member in several international conferences In the areas of micro & nano technologies and sensors. He serves regularly as reviewer in scientific journals and as invited speaker in conferences/summer schools. He is author of >120 publications in international journals and holder of 3 patents.
