My research interest is mainly directed towards electronic excitations in semiconductor quantum structures, such as quantum dots or wires, and their optical properties probed by photoluminescence-spectroscopy based techniques. Modelling, including k·p theory, configuration interactions and finite-difference-time-domain simulations, complements the experimental investigations. A particular focus is devoted to the optical polarization and its relation to the electronic structure.

A better understanding of the optical properties of quantum structures is vital for developing brighter and more energy efficient light sources. Moreover, a single quantum dot acts as non-classical light source, emitting single or correlated photons, of interest for future cryptography and computing applications.
