Our reserach activites focus on light-matter interaction in novel materials, in particular graphene and related two-dimensional crystals - such as transition-metal dichalcogenides - , carbon nanotubes, and semiconductor nanostructures. We use optical and vibrational spectroscopy with focus on high spatial resolution, resonance effects, and in-situ methods, in combination with density-functional theory computations. Our recent work addresses the structural, electronic, and optical properties of 1D and 2D materials, in particular the effect of interlayer interaction, interfaces, and chemical functionalization.

Some of our research activities are currently part of the collaborative research center SFB 953 „Synthetic Carbon Allotropes“ and of the DFG priority programme SPP 2244 „2D Materials – Physics of van der Waals [hetero]structures“.
