Bo Xiong

PhD candidate @ IMPRS-IS & University of Stuttgart

I am a fina-year Ph.D. candidate at International Max Plank Research School for Intelligent Systems (IMPRS-IS) and the University of Stuttgart, Germany, under the supervision of Prof. Steffen Staab. My PhD was funded by the Marie Sklodowska-Curie PhD Fellowship.

My research centres on machine learning with a special focus on modeling and understanding data with complex structure (e.g., social networks and knowledge graphs). For this purpose, I’m combining fundamental research on geometric representation learning, graph embeddings, neuro-symbolic AI, and language modeling.
