About me

After receiving my PhD in theoretical computer science under supervision of Christian Sohler, I am now postdoctoral researcher at the Statistics department of TU Dortmund in the group led by Katja Ickstadt.

I am principle investigator in a joint project on large-scale and high-dimensional regression problems within the collaborative research center SFB 876 and I am happy to advise Simon Omlor as my first PhD student.

Being a PI in the interdisciplinary research area From Prediction to Agile Interventions in the Social Sciences (FAIR) offers me a great opportunity to transfer and further develop innovative statistical and data science methods for their application in the social sciences.

Last but not least, I am happy to help building up the Dortmund Data Science Center in the position of its managing director.

Research interests

I am mainly interested in the design and analysis of algorithms for tackling the challenges of massive data and high dimensionality. I am also interested in collaborating on possible applications. My research involves several scientific fields such as

  • streaming and distributed algorithms,
  • randomized linear algebra,
  • machine learning,
  • computational statistics,
  • computational geometry,
  • convex optimization.
