Summary
👤
Senior🎓
Top SchoolMatthieu Schaller is an Assistant Professor and computational astrophysicist with 13 years of experience building high-performance, particle-based simulation software and leading the development of the highly-parallel SWIFT code for cosmology and galaxy formation. His work bridges theoretical physics and hands-on HPC engineering, including GPU acceleration, smoothed particle hydrodynamics, and computational fluid dynamics applied to dark matter and fundamental physics. Based at Leiden University, he combines academic research (PhD in numerical galaxy formation) with substantial software stewardship, maintaining a research-grade codebase used by the community. Notably, he brings industrial CFD experience and a multilingual Swiss academic background, enabling pragmatic solutions to large-scale numerical and performance challenges.
