We investigate the ultrafast phenomena of light-matter interaction on the nanoscale by means of real-time time-dependent density-functional theory. 

Our research comprises organic molecule and complexes, low-dimensional materials, and also inorganic/organic interfaces, as part of our project within the CRC 951 "HIOS".

We also involved in the SMART project financed by the VolkswagenStiftung as part of the program Digitalization in the Natural Sciences. Our aim is to take advantage of digitalization to gain unprecedented understanding of the ultrafast dynamics in various materials.

We are particularly interested in disclosing the fundamental mechanisms ruling the interaction between electronic and vibrational degrees of freedom in systems excited by ultrafast laser pulses.
