I am a Ph.D. student in Computer Science at University of Cambridge, where I am advised by Cecilia Mascolo. I work in the fields of multi-modal machine learning, mobile sensing and human-computer interaction. My research is supported by the Embiricos Trust Scholarship at Jesus College, Cambridge.
Previously, I worked in Barcelona as a Data Scientist at Qustodio and as a Research Intern at Telefonica Research, both during my Master studies at the Aristotle University of Thessaloniki. During my Bachelor studies at Ionian University, I worked as a Mobile Software Engineer at CERTH, a national research center.

Composing music and text with Recurrent Neural Networks
Training deep neural networks on massive amounts of musical notation (irish folk) and literature (Shakespeare's oeuvre) and letting them create their own art. Essay in Greek but you can still see/listen to the results.
Personal
Non-academic things about me: I love music, both playing and listening. Lately, I have been into art rock—indie folk. I am accordionist by training, but in recent years I've been playing mostly piano and ukulele. I have performed in classical orchestras, colleague groups and critically acclaimed indie bands like The Children of the Oldness (aka Kore Ydro). You can listen to the album I participated, "Consortium in Amato", here. I appreciate art and design and love to geek out over film directors and cinematography techniques. Sometimes I associate still depictions of the real world with words, lyrics or people. A subset of them is on Flickr. Lastly, and perhaps most importantly, I'm always on the lookout for ways to move items from the "non-academic list" to the "academic list"—let me know if you'd like to help!
