PhD in theoretical physics specializing in computational many-body methods (tensor networks, exact diagonalization, Monte Carlo). My work focuses on moiré systems and large-scale numerical simulations, and I enjoy building high-performance Julia libraries for scientific computing, quantitative modeling, and industry applications.

• Researcher at the University of Wuerzburg working on moiré materials and strongly correlated electrons using tensor-network and Monte Carlo methods.
• Interested in roles at the intersection of physics, software engineering, and quantitative finance, especially where numerical modeling, HPC, and rigorous data-driven decision making matter.

• Languages and tools: Julia, Python, Linux, HPC/MPI, Git
• Methods: Tensor networks (MPS/iMPS), exact diagonalization, Monte Carlo for quantum many-body systems
• Strengths: Numerical optimization, algorithm design, scientific software architecture, open-source collaboration

• Maintaining and developing many-body methods and generic Julia packages in the open-source organization ManyBodyLab:
  • Infinite tensor-network algorithms (e.g. iDMRG, MPO-compression) based on ITensors.jl
  • MPI-parallelized tensor-network algorithms in MPSKitParallel.jl
  • High-performance exact diagonalization tools
  • Monte Carlo for quantum many-body systems using Carlo.jl
• Designing modular backends to support multiple tensor-network libraries, improving flexibility and reuse across projects and reducing duplication in downstream codes.
  • TensorKitAdapters.jl & MPSKitAdapters.jl
• Contributing to MPSKit.jl and ITensors.jl, abstracting code and improving performance and maintainability.

• Applying physics-inspired numerical methods to:
  • Quantitative finance (stochastic simulation, time-series modeling, portfolio and risk analysis)
  • Large-scale scientific computing and optimization
• Building robust, well-documented open-source tools that can be used beyond a single research project.
