My research is focused on identifying exotic states of matter using transport and optical probes. I am working on correlated electronic systems, topological materials, superconductors and magnetic materials. I combine ab-initio and phenomenological approaches for the prediction and investigation of material properties. In correlated phases of matter, quantum geometry plays an important role, with profound experimental and technological consequences. This is exemplified in low temperature transport in topological antiferromagnets and the photocurrent response of time-reversal breaking superconductors.
