This is the personal webpage of Giorgos Spathoulas.

I am a computer security researcher and member of the teaching staff of Department of Computer Science and Biomedical Informatics of University of Thessaly. My main research interests are post processing of intrusion detection alerts and privacy in the web 2.0 and social networks.

Research

I am mainly interested in computer security. My main focus is network security and especially network intrusion detection systems. I work on post-processing of intrusion detection alerts, in order to improve their quality.

Apart from that I am also interested in privacy in modern web. I am working on anonymization techniques, homomorphic encryption and decentralization of existing services through disruptive technologies such as the blockchain.

I am also interested in security and privacy issues arising in the internet of things and big data areas.
