Nolwenn Bernard is a postdoctoral researcher at TH Köln (University of Applied Sciences). She jointly works with the Institute of Data Science, Engineering, and Analytics (IDE+A), and the Institute of Information Science. In 2025, she obtained my PhD in Computer Science from the University of Stavanger, Norway, under the supervision of Prof. Krisztian Balog.
Her main research interest revolves around the use of user simulation to develop conversational agents assisting users in finding relevant information.
