Experience

  1. AI Research Scientist Intern

    Meta FAIR
    I work within the Omnilingual Machine Translation team to expland the language coverage of MT systems well beyond their current capacity.

  2. AI Research Scientist Intern

    Apple
    Contributed to the Machine Translation team within the AI/ML division, primarly focused on Prosody Evaluation and Speech Translation. My research, which was published in WMT 2024, showed that although current state-of-the-art Speech Translation systems do have a understanding of prosody, they rarely leverge it in practice, indicating significant room for improvement.

  3. AI Research Scientist Intern

    Dolby
    Conducted research on Audio-Visual Representations and Contrastive Learning. Also contributed to a project on Video-to-Audio Generation. The corresponding research papers were published at ICASSP 2025 and ECCV 2024.

  4. AI Research Scientist Intern

    Zeta Alpha
    This internship was part of my MSc thesis. I worked on passage ranking and answer style transfer for complex question answering using transformer-based models.

  5. Financial Analyst Intern

    Eurobank
    My work during this internship focused on analyzing financial statements, adjusting funding limits and evaluating business plans of local businesses in Athens.

Education

  1. PhD in Artificial Intelligence

    UPC Barcelona
    Supervised by José A. R. Fonollosa and Marta R. Costa-jussà, I researched several topics within Speech Translation, including speech segmentation, data augmentation, efficiency inference, transfer learning, and zero-shot learning, and published in top-tier conferences including ACL, EMNLP, ICASSP, and InterSpeech.

  2. MSc in Artificial Intelligence

    University of Amsterdam
    Graduated cum laude with a GPA of 8.3/10. Through advanced elective courses, I specialized in sequence modeling, deep learning, transformers, and NLP. Thesis: Complex Question Answering by Pairwise Passage Ranking and Answer Style Transfer. → Thesis PDF

Projects

AI DJ Project | 2021

This project features an AI DJ system designed to perform a collaborative back-to-back set with a human artist. Uniquely, the system is sound-agnostic; it uses a language model to understand the sentiment of YouTube comments to find songs with a similar "feeling" to the recent track history. The project was showcased at the various events including S+T+ARTS Festival in Barcelona and Sonar+D in Lisbon.
