In my PhD, I am researching how machine learning can be employed to improve compiler optimizations.

Research Interests

  • Interpreters, compilers and virtual machines
  • Machine learning
  • Compiler optimizations



Apart from presenting publications at conferences, I have given talks on my work on other occasions as well.
  • GraalCGO 2021: Improving Compiler Optimizations by Employing Machine Learning
  • VMM 2020: Let Data Drive Compiler Optimizations


These are the projects I am currently working on or worked on in the past.

  • GraalVM, a universal virtual machine for running applications written in different programming languages.
  • Sulong a high-performance LLVM bitcode runtime built on the GraalVM by Oracle Labs.


  • Winner of the SPLASH 2020 Student Research Competition in the Graduate category
  • Würdigungspreis des Bundesministeriums für Bildung, Wissenschaft und Forschung für die besten Diplom- und Masterabschlüsse 2019


These are the courses that I am currently giving or have given in the past.
