Christian joined the group in May 2021 after received his Ph. D. at the University of Münster. There he worked on dark matter searches and double-weak decays in the XENON1T detector.  Now he focuses on the XENONnT and XLZD experiments for direct dark matter detection. Moreover, he works on passive dark matter and neutrino detectors based on colour centres in crystals. In his free time he enjoys hiking, brewing coffee and playing the guitar.
