Short Bio

My name is Kostas Stefanidis and I am an Associate Professor at the School of Information Sciences of the Tampere University, Finland.

Prior to that, I was a research scientist with the Information Systems Lab of ICS-FORTH, Greece, and a postdoctoral researcher at the IDI Dept. of the Norwegian University of Science and Technology, and at the CSE Dept. of the Chinese University of Hong Kong. I hold a PhD in CS from the University of Ioannina in Greece.

My research interests lie in the intersection of databases, information retrieval, and the Web.
