Scholar Spotlight: Bo Xiong

IMPRS-IS aims to recognize the outstanding accomplishments of its doctoral researchers through our scholar spotlight. We would now like to highlight some of the achievements of IMPRS-IS scholar Bo Xiong who won a Best Student Paper Award at the International Semantic Web Conference (ISWC 2022), the Faculty Publication Award 2022 at University of Stuttgart for his paper titled Pseudo-Riemannian Graph Neural Networks in NeurIPS 2022

Bo Xiong joined IMPRS-IS in March of 2021 as a doctoral researcher at the Analytic Computing Department of University of Stuttgart under the supervision of Prof. Steffen Staab. He is also an Early Stage Researcher under the Marie Skłodowska-Curie European Training Networks (ETN). His research lies in machine learning on relational and graph-structured data. His goal is to develop novel models and techniques that transform discreate, symbolic, and graph-structured data (e.g., networks and knowledge graphs) into continual geometric spaces, so as to enable the intergration of learning and inference. 

Bo Xiong won a Best Student Paper Award for his paper titled Faithful Embedding for EL++ Knowledge Bases at the International Semantic Web Conference (ISWC 2022), a premier conference in semantic web and linked data community. One of his NeurIPS paper on Pseudo-Riemannian Graph Neural Networks received the Faculty Publication Award at University of Stuttgart for the year 2022. He has published and co-authored several papers in top-tier conferences including NeurIPS, KDD, ACL, SIGIR and TheWebConf. 

Before his PhD journey, Bo has studied software engineering at Beijing Jiaotong University, Beijing, China, during which he has worked as a research intern at the Microsoft Research and Huawei Noah’s Ark Lab. In his spare time, Bo enjoys hiking, traveling and cooking.

We commend Bo for the great research he has been doing and thank him for his valuable contributions to our IMPRS-IS. We are proud to have Bo Xiong recognized as an IMPRS-IS Scholar Spotlight.
