Hi, I'm Johannes 👋

I build high-performance scientific software at the intersection of physics, machine learning, and HPC.

🚀 About me

  • Physics + ML + HPC with a focus on differentiable physics
  • Contributor to PyTorch (linalg (eig, eigh), cuSOLVER glue)
  • Working on RCWA-based optical simulations with autograd support

🔬 Current work

  • M.Sc. thesis @ Albert-Ludwigs-Universität Freiburg / Fraunhofer ISE
  • Focus: computational optics & optimization of photonic structures, experimenting with agentic AI
  • Preparing for PhD in computational physics / photovoltaics

🛠️ Tech stack

  • Python, PyTorch, CUDA
  • HPC (bwUniCluster, NEMO 2)
  • Scientific computing

📌 Projects

  • solwa – differentiable RCWA library (PyTorch-based)
  • Experimental work on inverse design & optimization

🎯 Interests

  • Differentiable simulation
  • GPU-accelerated scientific computing
  • Bridging physics models with modern ML workflows

🤝 Let's connect
