I am interested in quantum many-body systems, particularly in one or two dimensions or on mesoscopic scales (~10 nm to microns). My research addresses well-known states of matter like Fermi liquids and superconductors as well as more exotic ones such as topological insulators and spin liquids.
I often try to understand a system through the properties of the relevant low-energy excitations, for instance, Majorana quasiparticles in topological superconductors, exciton polaritons in semiconductor microcavity systems, or electronic shear sound in Fermi liquids. My work is often directly motivated by experiments or tries to propose novel ways of detecting physical phenomena.

We propose ways to experimentally characterize excitations in many-body systems, which are inaccesible in standard transport or spectroscopy experiments, e.g., using near-field techniques or NV centers in diamond.
We try to understand dynamical phenomena of polarons in condensed matter and cold atomic systems such as polaron drag (a novel form of Coulomb drag mediated by nonperturbative interactions) or metastable polaron states that can enable lasing.
We propose nanoscale superconducting hybrid structures as platforms for topological superconductivity and topological quantum computing and investigate unconventional Josephson effects in magneic Josephson junctions.
