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.
I'm Witold Niewiem
