I am a senior Ph.D. student at Paderborn University, advised by Eric Bodden. I work on scaling precise static code analyses on large-scale code bases, mainly through sparse data-flow and pointer analyses. I lead the development of the SootUp static analysis framework.

Resarch Interests

I am interested in static program analysis. More specifically I focus on:

  • Optimization techniques for the static analysis of real-world code bases
  • Program-specific applications of such optimizations
  • Techniques for specifying program analyses
