I am an Associate Professor at the Adaptive Quantum Optics Chair. My research revolves around the study of open quantum systems.

Short biography

In 2006, I completed my master’s degree in physics at RWTH Aachen. In my master's thesis, I theoretically investigated statistical properties of magnets and crystal surfaces. For my PhD, I switched to experimental quantum optics working on the Bose-Einstein condensation of photons at the University of Bonn. After finishing my PhD in 2011, I continued to work at the University of Bonn as project leader for the photon Bose-Einstein condensation experiment. In 2015, I moved to ETH Zürich to work on semiconductor optomechanical nanostructures. In September 2017, I started as Assistant Professor at the University of Twente. My research revolves around the study of open quantum systems.
