General - Aim of the Department

Computer Science, a relatively new science, started as a topic of limited scope, restricted to the automation of mathematical computations. Soon, however, it evolved into an exciting mixture of theory and technology, having as its central study theme the problem and its calculation, extending from the study of the theoretical (and philosophical) aspects of abstract problems to the effective solution of specific problems with practical significance, through software or hardware design. It is worth noting that the fundamental principles behind the theory of Computer Science emerge from the works of Ancient Greeks.

The dramatic advances in Computer Science and its contributions to the scientific community, as well as the impact of Computer Engineering onthe everyday life of millions of people, allow us to predict with certainty that the new fields of study will contribute to the further scientific progress of Computer Science and Engineering and other future sciences, and they will constitute the basis for solutions to real-life problems, and the development of new technologies.  Those emerging fields of study include: parallel processing (the construction and programming of ultra fast computers using multiple - sometimes thousands of - processing units); the automation of formal reasoning and logic along with their usage in the systematic design and validation of software; robotics with its exciting applications in industry and space sciences; the construction and deployment of distributed information systems; the theory of algorithms which covers the whole computational spectrum; the design of software and integrated circuits; the analysis of big data for extracting useful knowledge about medicine, finance, or urban living; the information extraction and retrieval from the Web, and online social networks; the integration of mobile devices in the everyday life, and many others.

The Department of Computer Science & Engineering aims at contributing to the scientific advances in every aspect of Computer Science and Engineering. To this end, the Department has set three key objectives: recruitment of prominent faculty members, expansion of its research activities and continuous improvement of its postgraduate and undergraduate programmes. It is our belief that the students of an academic department constitute the basis for its existence and its development while its graduated students constitute the driving force for society's development. As a consequence, one of the primary goals of the Department is to equip its students, through its study programmes and its numerous scientific activities, with an appropriate body of knowledge which will allow them, upon graduation, to occupy vital professional, research or academic positions in the broader area of Computer Science and Engineering.
