Hello! I am a final-year Ph.D. student at the Electrical Engineering department at EPFL and a research assistant at HEIG-VD, in Switzerland. My Ph.D. advisor is Andrei Popescu-Belis. I am interested in machine translation and large language models. I also have a growing interest in machine translation evaluation.

During my Ph.D. I interned at Google in the Google Assistant team in Zurich, Switzerland. I also did an internship at Amazon Web Services (AWS) in Santa Clara, CA, working with the Amazon Translate team.

Before coming to Switzerland, I obtained my diploma (combined BEng and MEng) in Electrical and Computer Engineering and my MSc in Data Science and Machine Learning from the National Technical University of Athens in Athens, Greece. In my Master’s thesis, I worked on Adversarial Fine-Tuning of Pretrained Language Models under the supervision of Andreas Stafylopatis. During that time I was also working as a Machine Learning Engineer at DeepSea Technologies.
