The organizational structure of ICCS is a key reason of its success. Following a lean structure, the Institute is directed by its director and a 5-member board supported by an administration team. On the research/technical side, there is a single layer hierarchy comprising individual and independent research teams, forming up the so called ‘Research Units’. Currently, within ICCS/NTUA there exist more than 30 Research Units covering all domains of the School of Electrical and Computer Engineering. Each Unit is headed by a faculty member of ECE-NTUA or the appointed ICCS/NTUA researcher. The typical size of each Unit is relatively small including PhD students, post-doctoral researchers and support personnel.
