has studied Mathematics, Engineering and Chemistry at the Universities of Magdeburg, Braunschweig and Münster. In 2013 he received his master’s degree at the Institute for Physical Chemistry at TU Braunschweig. In the following, he worked on modelling of on-surface coupling processes and the development of embedding methods to combine periodic and non-periodic quantum chemistry frameworks for which he received his PhD from the University of Münster in 2017 (“Quantum-chemical investigation of on-surface reactions and the foundation of periodic density embedding”). Afterwards he moved to the University of Luxemburg for a two-year Postdoc position, where he implemented semi-empirical methods to describe Van-der-Waals interactions in different quantum chemistry codes. From 2020 to 2022, he worked in industry in the field of simulation data management. In August 2022, Dennis joined the group of Andreas Pflug at the Fraunhofer Institute for Surface Engineering and Thin Films (IST), where he is working on development and application of the PICMC code for the simulation of thin film coating processes.
