Hi, my name is Stefan Neumann and I am a tenure-track assistant professor at TU Wien, generously funded by a WWTF VRG grant. My main research areas are as follows:

  • 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.

Previously, I was a WASP assistant professor at KTH Royal Institute of Technology and a post-doc in the group of Aris Gionis. I received my Ph.D. from the University of Vienna, advised by Monika Henzinger. During that time, I visited Eli Upfal at Brown University for six months.

My Ph.D. thesis won the Heinz Zemanek Award from the Austrian Computer Society and an Award of Excellence from the Austrian federal government.

You can find more information including all of my publications in my CV.
