David Kletz

David Kletz is a postdoctoral researcher at IDSIA, working within the Natural Language Processing (NLP) team. He earned his PhD in NLP in February 2025 from Sorbonne-Nouvelle and Université Paris Cité (UPC), where his research focused on the representation and understanding of negation in pre-trained language models. His current work explores the application of large language models (LLMs) to enhance information retrieval for specialized documents and domain-specific tasks. Building on his doctoral research, he remains deeply engaged in analyzing model knowledge and improving model interpretability, aiming to make AI systems more transparent and explainable.
