Christian Gollwitzer

Dr. Christian Gollwitzer is a researcher at the Physikalisch-Technische Bundesanstalt (PTB), where he heads the X-ray radiometry working group since 2019. His work focuses on advancing precision measurement techniques in X-ray science with applications in biomedical research and materials characterization.

Education:

• Studied physics at the University of Bayreuth and Charles University in Prague
• Received doctorate from University of Bayreuth in 2010 specializing in magnetic gels and liquids

Dr. Gollwitzer's research spans Materials Science, X-ray Imaging, and Nanotechnology, with emphasis on developing innovative metrological solutions. His team pioneers methods in computed tomography, small-angle X-ray scattering, and radiography, particularly focusing on simplifying nanoparticle structural analysis through gradient-based contrast techniques. This work bridges fundamental physics with practical applications in medical imaging and advanced materials.

He has advised doctoral researcher Raul Garcia Diez, whose dissertation on nanoparticle visualization earned the Adlershof Dissertation Prize in 2017. Dr. Gollwitzer's collaborative approach involves international partnerships to solve complex measurement challenges in socially relevant domains like biomedical technology.

At PTB, he leads the X-ray radiometry working group, driving research in high-precision X-ray measurement standards. The team develops cutting-edge instrumentation for industrial and medical applications while maintaining PTB's role as Germany's national metrology institute for physical-technical standards.
