My research focus is on algorithms for data science and for social network analysis. In particular, I am interested in the following topics:

Foundations of data science: I develop practical data science algorithms with provable guarantees. I am particularly interested in the beyond worst-case analysis of algorithms.

Social network analysis: I study how interventions, such as timeline algorithms, influence the polarization and the disagreement in (online) social networks.

I am also generally interested in graph algorithms and (dynamic) data structures.
