I am an Associate Professor at the Adaptive Quantum Optics Chair. My research group investigates physical phenomena at the interface between thermodynamics and quantum mechanics in optical and optomechanical systems.
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 team investigates physical phenomena at the interface between thermodynamics and quantum mechanics in optical and optomechanical systems. Our current research projects are:
- Photon Bose-Einstein condensation
- Optical spin glass simulation
- Engineered thermal reservoirs
