Combining quantum physics and gravity is one of the greatest unresolved puzzles in modern physics. Theoretical progress is hindered by a lack of experiments, and experiments are hindered by the typical inaccessibility of the quantum gravity regime. The group finds itself right in the middle of this vicious cycle, using precision measurements to experimentally access this regime and in turn inform theories.

Precision metrology encompasses techniques and concepts from many different fields. Experiments make heavy use of cavity optomechanics, electromagnetism, quantum optics, and electronics, whereas on the theory side, we think a lot about quantum physics, stochastic processes and anything else that is necessary to understand and design the experiments.
