Research Agenda: The main topic of our experimental research is the physics of low-dimensional solid-state systems. We focus on investigating 1D-systems (carbon nanotubes, confined carbyne), 2D-structures (graphene, transition-metal dichalcogenides), and their heterostructures by confocal and tip-enhanced Raman spectroscopy. We want to understand the physics that governs the behavior of these materials, achieve active control over their optical properties, and use them to explore advanced concepts like molecular optomechanics. We are further interested in method development for tip-enhanced and surface-enhanced Raman scattering.
Short Bio: I received my Ph.D. from the Freie Universität Berlin (Germany) in 2015 for the work on plasmon-enhanced Raman scattering on graphene and carbon nanotubes. After PostDocs in the group of Aravind Vijayaraghavan at the University of Manchester (UK), the Photonics Laboratory led by Lukas Novotny at ETH Zürich (Switzerland), and with Kirill Bolotin at Freie Universität Berlin (Germany), I am leading a research group at the Humboldt Universität Berlin funded by the Emmy-Noether Initiative of the German Research Foundation since 2021.
