I am a professor of Data Science in the Database and Web Technologies group at Aalborg University's Department of Computer Science and a member of its Center for Data-Intensive Systems (Daisy) as well as affiliated with the group of Artificial Intelligence and Machine Learning and Aalborg University's AI for the People Center.

My research is rooted in data and knowledge engineering and spans theory, algorithms, and applications of Data Science including graph databases, knowledge graphs, querying, analytics, and machine learning.

Prior to joining Aalborg University, I was a postdoc in Gerhard Weikum's Databases and Information Systems group at the Max Planck Institute for Informatics in Saarbrücken, Germany, and received my PhD in Computer Science from Ilmenau University of Technology, Germany.
