About Me


I am a senior researcher with Telefonica Research in Barcelona. Prior to joining Telefonica I was a postdoc fellow at Harvard University and a Marie Curie postdoc fellow at Boston University. I got my PhD in computer science from the University of Athens in 2004. In my latest work I’ve been focusing on issues of privacy and transparency on the web. I am the chief scientist and one of the co-founders of the Data Transparency Lab.
