About Me

I work as a Ph.D. student at the department of programming languages under the supervision of Prof. Dr. Peter Thiemann.

Research Interests

  • Type systems and formal logic
  • Interactive theorem proving with systems based on dependent type theory like Agda, Coq, or Lean
  • Typed functional programming, Haskell, ML
  • Substructural types, session types, Rust
  • Compiler construction and optimization
  • Development tools and structural code editors
  • Language integration for GPU programming supporting code that is polymorphic about whether it's used on the CPU or the GPU
