Biography:

Before coming to Cambridge, I did postdocs at Yale University (Steven Girvin) and the University of Basel (Christoph Bruder). Before that, I did a DPhil at the University of Oxford supervised by Keith Burnett and supported by the Rhodes Trust. Before that, I read physics at Bonn University, spent time in Uppsala, and wrote my diploma with Pierre Meystre at the University of Arizona.

Research Interests

A central theme of my research is quantum coherence in atomic, mesoscopic, and optical systems and, in particular, how to exploit it for fundamental table-top science and future quantum technologies. This puts my work at the interface of theoretical quantum optics, atomic and laser physics, condensed matter theory, and quantum information science. In particular, I have worked on strong correlations, quantum-enabled technology, and control of ultracold atomic gases, superconducting circuits, and cavity optomechanical systems.
