Research interests

My primary research field is the dynamics of non-interacting particles, with a special emphasis on the generation of (ideally) indistinguishable photons and their interference in waveguide structures. Please have a look at my project page for more information on this.

My further research interests are experimental tests of quantum mechanics via precision interferometry (see the topic multi-path interference on our group page), the development of photon sources for quantum-enhanced spectroscopy and photonic quantum simulation as well as emulation of quantum phenomena with classical light.
