Precision in the production of EUV laser systems — from the lab bench to the series-production floor.

Physicist with a background in solid-state physics, optics, and atomic physics. Today, as a production engineer at TRUMPF, I'm responsible for qualifying mission-critical assemblies for EUV laser systems.

About me

I emigrated to Germany at 18. After learning the language, I moved to Stuttgart to study physics. Over the course of my degree I focused in particular on solid-state physics, optics, and atomic physics.


My academic path exposed me to a broad range of measurement methods and analysis techniques — I'm drawn to optimizing and automating measurement workflows, which lets me put my programming skills to use. Precision and organization are central to how I work.
