Hi, I am a researcher in visual analytics and human-AI interaction.

I am at the CVAST lab and employed in the Bilateral AI Cluster at TU Wien. Earlier, I was part of the DBVIS group at the University of Konstanz. I am interested in heterogeneous data, network analysis, geographical data science, the digital humanities, and explainable AI.

Reach out if you would like to discuss research ideas, collaborations, or thesis supervision.
