About

I am a PhD student in the Computer Science Department at Boston University, fortunate to be advised by Derry Tanti Wijaya and Sarah Adel Bargal. My interests lie in the areas of Machine Learning and Natural Language Processing. My research focuses on developing data-efficient models and techniques for learning from highly complex data, including text, time-series, images, videos and graph-structured data, for a broad spectrum of applications, such as Machine Translation, Social Media Analytics and News Framing. I am particularly interested in learning in low-resource settings, and also in leveraging explainability methods for model improvement.

Currently I am a Research Intern in the Google Translate team, working on models for Direct and Zero-shot Neural Machine Translation.

Prior to my PhD, I completed my undergraduate studies at the National Technical University of Athens, from which I hold a diploma in Electrical and Computer Engineering. In parallel to my academic path, I have contributed to a variety of product- and academic research oriented projects in the industry as a Developer and a Researcher, and have previously worked as an intern at SRI International, Electronic Arts and Nokia, as well as collaborated with Johnson & Johnson and Mentat.

For more details you can see my CV. Feel free to contact me for questions or any potential interest.
