Jiaxuan Yu is a Master’s student in Computer Science (Artificial Intelligence) at Leiden University, under the supervision of Dr. Saber Salehkaleybar. Her research centers on language representation and uncertainty in communication, with a focus on how humans express hedging, confidence, and ambiguity. She is particularly interested in the uncertainty and interpretability with language expression, and how natural language processing methods can capture these signals to build more interpretable, robust, and human-centered language technologies that support reliable understanding and generation in real-world, data-driven applications.
