Yougang Lyu
I’m a PhD student at the University of Amsterdam . I have been very fortunate to be advised by Prof. Maarten de Rijke and Prof. Zhaochun Ren.
My current research focuses on large language model (LLM) alignment and its applications in information retrieval and recommender systems. I aim to narrow the gap between AI research and real-world applications by advancing the development of next-generation trustworthy language agents.
