I am a full professor of Data Management at TU Wien‘s Databases and Artificial Intelligence research unit. Prior to joining TU Wien, I have been a full professor at Aalborg University, a postdoc at the Max Planck Institute for Informatics in Saarbrücken, and received my PhD in Computer Science from Ilmenau University of Technology.

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. In the past couple of years, I have gained extensive experience in interdisciplinary data science in collaborations with colleagues from bioscience, health, and environmental assessment.
