I am a PhD student at ILPS, UvA, under the supervision of Prof. Maarten de Rijke.
My daily advisor is Edgar Meij.

My research focuses on improving information access using both structured and unstructured sources of information. I am currently working on making knowledge graphs more accessible to the end-user in search applications by describing & contextualizing their content.

Background

I did my bachelor in computer science at the University of Athens. I then obtained my MSc in artificial intelligence from the University of Amsterdam. I did my master thesis on explaining entity relationships in collaboration with Yahoo Labs. The thesis won two national thesis awards (STIL & KION AI). After that I worked at Signal Media as a data scientist before joining UvA again to start my PhD in July 2015.
