I'm a Postdoctoral Researcher at the EdinburghNLP group (part of the Institute for Language, Cognition and Computation, School of Informatics, University of Edinburgh). I am currently working in collaboration with Prof. Mirella Lapata and Megagon Labs.
My research focuses on neural models for text understanding and generation with applications on summarization, sentiment analysis, question answering and information retrieval.
I succesfully completed my PhD in April 2019, under the supervision of Prof. Mirella Latapa and Prof. Charles Sutton (Thesis: "Weakly Supervised Sentiment Analysis and Opinion Extraction"). Before my PhD, I obtained a MSc in Artificial Intelligence with distinction from the University of Edinburgh. My MSc Thesis was supervised by Prof. Victor Lavrenko. I received my undergraduate degree on Informatics and Telecommunucations from the National and Kapodistrian University of Athens.
