Christodoulos Chamzas was born in Komotini, Greece. He received the Diploma Degree in Electrical and Mechanical Engineering from the National Technical University of Athens, Athens, Greece, in 1974 and the M.S. and Ph.D degrees in Electrical Engineering in 1975 and 1979 from the Polytechnic Institute of New York, Farmingdale.

From 1979 to 1982 Dr. Chamzas was an Assistant Professor with the Department of Electrical Engineering at Polytechnic Institute of New York. In September 1982 he joined AT&T Bell Laboratories, Holmdel, NJ, where he was a member of the Visual Communications Research Department until 1990, where he worked on adaptive systems, mobile communications, multimedia image databases and image coding. Since September 1990, he is a member of the Faculty of the Electrical Engineering Department at Democritus University of Thrace, where he is Director of the Electric Circuits Analysis Lab. (1991-2005), of the Sector of Electronics and Information Technology Systems (1997-1998 and 2012-2014) and of the Image Processing and Multimedia Unit ( http:\\ipml.ee.duth.gr ) and of the CULTURAL AND EDUCATIONAL TECHNOLOGIES INSTITUTE (www.ceti.gr) (1998-2012) . During 2001-2003, he was elected to the position of the Department Head of the Electrical and Computer Engineering Department at Democritus University of Thrace (www.ee.duth.gr ). He has been a major player in the definition, design and implementation of the CCITT/ISO (JBIG, JPEG, etc), standards for coding, storage and retrieval of images (color & bilevel) an area where he holds six (6) international patents. In 1985-86, he was a visiting professor with the Department of Computer Science at the University of Crete, Iraklion, Greece. From 1994-1998, he was a member of the Telematics for Knowledge Working Party of EE, representing Greece. He has held summer positions in Greece, England, Portugal, as well as at Bell Laboratories. His primary interests are in cultural technologies, digital signal processing, image coding, multimedia and communications systems. He is currently interested in the implementation of 3D Digitization of Cultural objects and their dissemination with new technologies, multimedia image data base algorithms and schemas as well as content retrieval. He has over 800 citations to his work (over 1800 in Google Scholar).

Dr. Chamzas is a member of the Technical Chamber of Greece, Sigma Xi, an Editor in the IEEE Transactions of Communications (1989-1996) a Distinguished Member of the Technical Staff of AT&T Bell Laboratories and a Senior Member of IEEE.

 

He was the Scientific Program Manager or the Scientific Group Manager in a number of European or National Projects in the area of Cultural Heritage. Indicatively the following are mentioned. iGuide-Explore the Unexplored Greece, "STACHEM", Science and Technology for Archaeology and Cultural heritage in the Eastern Mediterranean, CARARE- Connecting ARchaeology and ARchitecture in European, 3D-Icons (3D digitization of European Cultural Heritage).
