Summary
👤
Senior🎓
Top SchoolAlexander Täschner is a physicist-turned-software-savvy research engineer with over 11 years’ experience in nuclear and hadron physics, vacuum and cryogenic systems, and advanced data acquisition and analysis at GSI in Darmstadt. He holds a Diplom and a Dr. rer. nat. (magna cum laude) in Physics and has a long academic career at the University of Münster before moving to applied research. Alongside experimental work he contributes code to prominent open-source projects—improving Microsoft’s vcpkg C++ package manager and enhancing Microsoft.Data.Sqlite features—bringing automation and robust data I/O to scientific and production-grade tooling. He bridges deep lab expertise with practical software engineering, enabling reproducible data pipelines and incremental blob I/O for large or low-temperature experiments. Colleagues rely on him for tackling cross-disciplinary problems that require both hands-on instrumentation skills and careful, production-minded code.
