In July 2010 Michèle took up a Junior Professorship at the Centre for Quantum Engineering and Space-Time Research (QUEST) at Leibniz Universität Hannover, Germany. Before that she was a Research Fellow in the group of Prof. E. H. Huntington, University of New South Wales @ the Australian Defence Force Academy (Canberra, Australia). During this time her research was based in the following areas: Modern quantum feedback control of quantum optical systems, continuous variable quantum computing, generation of a comb of squeezed light, measurement induced entanglement, homodyne locking and detection.

Since Dec. 2016 is a professor of experimental physics at Leibniz Universität Hannover. The position carries the denomination “Non-classical laser interferometry”, where applications are of course aimed at future interferometric gravitational wave detectors, but also at precision metrology in quantum optics.

Her current research interests lie in the following areas:

  • quantum noise reduction schemes for interferometric gravitational wave detectors (e.g. coherent quantum noise cancellation; recycling techniques with micro-optomechanical oscillators)
  • non-classical light sources (high-frequency sub-threshold optical parametric oscillators)
  • laser physics (including laser stabilization, novel locking schemes, and non-linear optics)
  • precision metrology (obviously interferometric gravitational wave detection, but also stable high finesse optical resonators)
  • high-frequency large bandwidth low-noise photodetection (single and homodyne)
  • modeling of micro-optomechanical oscillators / membranes
  • classical, modern, and coherent control

Michèle is a long-term member of the LIGO Scientific Collaboration (LSC) (since around 2003, with a break during her PostDoc in Australia 2007 — 2010), and has been a Council Member of the LSC since 2015. She is currently Dean of the QUEST Leibniz Forschungsschule (a faculty-equivalent structure spanning different faculties of LUH), as well as acting co-speaker of the Cluster of Excellence “QuantumFrontiers”. In the two Clusters of Excellence “QuantumFrontiers” (QF) and “PhoenixD” (PxD) she is a Principle Investigator, and Topical Group Leader of the TG “Backaction-evading techniques” in QF.
