Professor Panagiotis E. Pintelas received his B.Sc. in Mathematics from the University of

Athens, Hellas, in 1971, and his M.Sc. and Ph.D. in Computer Science from the University

of Bradford, UK, in 1973 and 1976, respectively. Since 1995, he is an Professor of

Computer Science with the Informatics Division of the Dept. of Mathematics at the Univ. of

Patras. He was elected Head of the Division of Applied Mathematics and Informatics from

1991 to 1993 and 1998 onwards. In the recent past, he was with the Dept. of Computer

Engineering and Informatics, University of Patras, as a Visiting Scientist (1981-1984),

Lecturer (1984-1987) and Assistant Professor (1987-1991).

 

His research interests include Software Specification and Software Design, Software

Engineering, Computer Assisted Training and Education (CAL/CAI/CBT/ITS) and Open

and Distance Learning; in these fields he has numerous publications in international

scientific journals and conferences. He has co-ordinated or participated in numerous

basic research and development National and EU projects. He is a member of the British

Computer Society and of the British Association of Chartered Engineers and a member

of the Association for the Development of Computer-Based Instructional Systems (ADCIS).

He is in charge of the Educational Software Development Laboratory, the establishment of

which he proposed in 1992. Professor Pintelas, since 1998 is also involved with the Greek

Open University as author, editor and Academic in charge of the Informatics cycle of studies.
