Two projects in the DFG TRR 142/3 Tailored nonlinear photonics:
From fundamental concepts to functional structures:
A02 "Nonlinear spectroscopy of semiconductor nanostructures with quantum light" (Akimov (TU Dortmund), Meier);
A10 "Nonlinear strong-field dynamics of atomically thin transition metal dichalcogenides" (Lange & Ruppert (TU Dortmund), Meier).

DFG Project ME 1916/7-1, Semiconductor quantum wells excited by non-classical states of light: Interplay between photonic quantum correlations and many-body interactions in solid state systems, together with J-Prof. Polina Sharapova.

PI in the project "Photonisches Quantencomputing" (PhoQC), which is supported by the Ministry for Cuture and Science of the state of North Rhine-Westphalia.

Mobility grant by the Sino-German Center for Research Promotion (SGC) (joint venture of the National Natural Science Foundation of China (NSFC) and the DFG), Three­-Dimensional Microscopic Simulations of High-Harmonic Generation and Strong Field Phenomena in Semiconductors, together with Prof. Xiaohong Song (Hainan University).
