I'm Witold Niewiem

Welcome on my personal website

I am a metrologist specializing in precision alignment for particle accelerators. After completing my PhD at ETH Zurich and working at CERN Geneva, I now work at SLAC Stanford University developing advanced measurement and alignment systems using laser trackers and custom solutions. My work combines engineering, 3D spatial analysis, and programming. Outside the lab, I enjoy traveling and exploring science,  and nature.
