I am an Assistant Professor (currently moving to the Electrical and Computer Engineering Department) at the University of Patras. I received a PhD and BSc from the Electrical and Computer Engineering Department, University of Patras.
My research is related with investigating the influence of human aspects in the design and evaluation of information systems, with a special emphasis on usable security, user modeling and personalization systems, aiming to drive the development of bootstrapped IT solutions to the unique cultural, cognitive and individual characteristics of the end-users.Email: fidas AT upatras.gr :: LinkedIn Profile: https://www.linkedin.com/in/fidas
