Research interests

Indicative national and European research and development projects involving the members of the group are as follows:

  • Fuzzy mathematics.
  • Semantic web.
  • Visualisation of information.
  • Artificial Intelligence.
  • Retrieving information.
  • User customisation.
  • Cultural Informatics.
  • Social networks.
  • Intelligent cities.
  • Intelligent environments.

In addition to its research activities, the Laboratory contributes to undergraduate and postgraduate study programs of the Department by participating in the teaching of courses that are relevant to the subject and offering theoretical and applied theoretical issues within the academic obligations of the students.

Who we are

Dr. Manolis Walles, Assistant Professor of the Department of Informatics and Telecommunications, Founder and Director of the Laboratory, has a long experience of managing teaching and research structures since his previous career at the University of Indianapolis and the Foundation of the Hellenic World.

The character of the Laboratory is highly interdisciplinary, with the research interests of its professors and researchers embracing various fields of computer science as well as psychology, pedagogy, archeology and history.

Scientific work

The scientific work of the Laboratory is reflected in the publications of its members in scientific journals, conferences and books. The Laboratory members have cumulatively more than 200 publications and have received more than 4,000 reports. They have also been responsible for publishing numerous special volumes of magazines, collective book volumes and conference proceedings.


Publications of Laboratory members in scientific journals, conferences and books


The tools resulting from our research work and the graduate and diplomatic work of the students are freely available through the Laboratory’s website. These include, but are not limited to:

  • Application for visualization of uncertainty in word clouds
  • Application for organizing photographic files
  • Application for measurement and visualization of the research influence
  • Application for collection of bibliographic reports

Open Source

The Lab participates in the open source initiative and distributes, through its GitHub account, the code of the tools it develops.


We provide the source for most of our applications through our GitHub account.


ΓΑΒ LAB is located on the ground floor of the Faculty of Economy, Management and Informatics building at Sehi, which is part of the University of Peloponnese Campus in Tripolis.
