Guohui is an associate professor at the Department of Information Science and Media StudiesFaculty of Social Sciences at University of Bergen (UiB), Norway. Before joining UiB, Guohui worked as an assistant professor at the KRDB Research Centre for Knowledge and Data, Faculty of Computer Science at Free University of Bozen-Bolzano. He obtained his PhD degree in Vienna University of Technology and his MSc and BSc degrees in Peking University.

Guohui's current research focuses on Virtual Knowledge Graphs (VKGs), also known as Ontology-base Data Access (OBDA). His interests include theoretical investigation, system implementation, and industrial use-cases of VKG/OBDA technology. He is leading the development team of Ontop VKG system, which has been adopted in many academic and industrial projects.
