Hi, I’m Felix! 👋
I am a PhD student in Computer Science at the Technical University of Munich, supervised by Prof. Nils Thuerey and funded by the Munich Center for Machine Learning (MCML). My research is on differentiable physics simulators, neural emulators for PDEs and optimization theory. During my PhD, I interned at Meta Reality Labs in Zurich supervised by Ryan Goldade.
Before the PhD, I studied Computational Science and Engineering (CSE) at TU Munich with a focus on applied numerical methods, high-performance computing and machine learning. During this time, I was fortunate to be supervised by Dirk Hartmann while conducting industrial machine learning research at Siemens Technology as part of my working student position and master thesis. Initially, I studied Mechanical Engineering at the Technical University of Braunschweig from which I graduated with a bachelor thesis on explicit-adaptive finite volume solvers supervised by Fabian Sewerin.
I strongly believe in open science and open education which is why I created the YouTube channel Machine Learning & Simulation to cover advanced mathematical topics I am passionate about.
News
- September 2025: My paper “Neural Emulator Superiority: When Machine Learning for PDEs Surpasses its Training Data” has been accepted to NeurIPS 2025! I will be travelling to San Diego 🛩️. Shoot me a message if you want to meet up!
- June 2025: I will be joining Meta Reality Labs for a research internship this summer!
