Research interests

Our research in Attosecond Quantum Dynamics aims at revealing the dynamic behaviour of the quantum world within atoms molecules and solids that lead to macrocopic functionalities. We use attosecond soft x-ray pulses and quantum microscopy with single electrons to address fundamental problems such as molecular isomerization, phase transitions and superconductivity with applications across quantum sensing, energy harvesting and storage, efficient sensing and computing.
