Welcome

Adopt a Loggerhead sea turtle

I am an Assistant Professor in the Department of Cultural Heritage Management and New Technologies, University of Patras, and a Research Associate at the HCI Group of the Interactive Systems Laboratory. I received a PhD and BSc from the Electrical & Computer Engineering Department, University of Patras.

My research is related with investigating the influence of human aspects in cultural heritage informatics and usable & secure information systems aiming to drive the design and development of bootstrapped solutions to the unique cultural and cognitive characteristics of the end-users.
