Ion Androutsopoulos

Ion Androutsopoulos is a Professor of Artificial Intelligence in the Department of Informatics at Athens University of Economics and Business (AUEB), where he also serves as Head of Department. He is founder and co-director of AUEB's Natural Language Processing Group and an Adjunct Researcher at the Digital Curation Unit and "Archimedes" Research Unit of the Research Centre "Athena".

His research spans multiple dimensions of Artificial Intelligence with a focus on Natural Language Processing. Key interests include:

• Machine learning in NLP, particularly deep learning and large language models
• Question answering and retrieval augmented generation for document collections
• Dialog systems for new languages and knowledge domains
• Sentiment analysis and emotion recognition from text and speech
• Detecting toxic posts and disinformation online
• Image-to-text generation for medical diagnostics
• NLP applications in biomedical, legal, and financial domains

His recent publications demonstrate strong activity across medical AI (particularly ImageCLEFmed Caption competitions where his group consistently ranks 1st-2nd), legal NLP (LexGLUE benchmark), financial NLP (EDGAR-CRAWLER), and multilingual challenges. His work shows increasing emphasis on large language models, explainability, and practical applications.

Notable awards include:

• Top 2% scientist worldwide (Stanford University database, 2023)
• Multiple AUEB Excellent Teaching Awards (2017-18, 2021-22, 2023-24)
• Three consecutive BioASQ awards (2018-2020)
• Multiple 1st/2nd place rankings in ImageCLEFmed Caption competitions (2021-2025)

He actively organizes major events including the Athens Natural Language Processing Summer School (AthNLP) and SemEval tasks. His group maintains strong industry and research collaborations, particularly in medical AI applications where they've developed systems that generate diagnostic captions from medical images with state-of-the-art performance.
