Christian's research is dedicated to the photophysics and photochemistry of molecular functional materials and complex supramolecular systems. He uses a variety of state of the art quantum chemical methods and multiscale modeling to understand the electronic and optical properties of the mentioned materials. These properties include, e.g., absorption, emission, and light-induced dynamics.
Christian received his B. Sc. degree in physics with honors from the University of Paderborn in December 2010. Afterwards, he continued his studies in physics and in February 2011 he was awarded a fast-track fellowship within the GRK 1464 "Micro- and Nanostructures in Optoelectronics & Photonics" funded by the Deutsche Forschungsgemeinschaft to skip the master degree and start with his doctoral studies.
From February 2012 to June 2015, he was a regular PhD student in physics at the University of Paderborn within the GRK 1464. During his doctoral studies, he investigated the photophysics and photochemistry of conjugated polymers, graphene quantum dots, and perylene derivatives as conjugated systems and of diarylethenes as photochromic molecules using quantum chemical methods. From February 2013 to January 2015, Christian received a full PhD scholarship from the Friedrich-Ebert-Stiftung to fund his thesis work. In June 2015, he defended his PhD thesis "Photophysics and Photochemistry of Conjugated Systems and Photochromic Molecules" with distinction ("summa cum laude").
From July 2015 to July 2016, he was working as a postdoctoral researcher at the University of Paderborn. From August 2016 to March 2019 he was a postdoc in Igor Schapiro's research group at the Fritz Haber Center for Molecular Dynamics Research, The Hebrew University of Jerusalem, Israel. There he studied the photophysics of nucleobases by employing multi-reference methods and of photoreceptor proteins by using quantum mechanics/molecular mechanics (QM/MM). He was funded via a Return Fellowship from April to September 2019 working again in the group of Prof. Schumacher at Paderborn University and after this, he started as postdoctoral researcher in the group of Prof. Matysik, Institute for Analytical Chemistry, Leipzig University further investigating photoreceptor proteins and functional materials.
