Overview

I am a Professor of Physics in the Gravity Exploration Institute.

My main expertise and experience is in experimental gravitational physics research, in particular instrumentation for gravitational wave detectors. I am also interested in exploring how to apply precision interferometry to fundamental physics, as for example in the search for dark matter.

I am Prinipal Investigator to the consortium "Quantum-Enhanced Interferometry for New Physics", in which we search for new particles beyond the standard model and for experimental signatures of quantization of space-time or semi-classical gravity. More on our consortium can be found here:

I co-edited the 2-volume book "Advanced Interferometric Gravitational-Wave Detectors" (World Scientific, 2019):

Advanced Detector Book

and published a book introducing a brief history of gravitational-wave research, the workings of the detectors, and the first detections for a general audience (CRC Press, 2019)

Gravitational-Wave Book

the German version of the book can be found here (C.H. Beck, 2018):

Research

My research interest is in instrumentation for gravitational wave detectors, and how these complex machines can be made more sensitive and reliable. Interferometric gravitational wave detectors embody phyiscs and engineering from many disciplines, like mechanics, optics, control systems, electronics, computing, solid state physics, and vacuum technology.

Examples of my particular interests are: Improving the readout methods with which gravitational wave information is obtained from the optical output of what we call the main interferometer, understanding and improving the complex alignment system of gravitational wave detectors that hold all optics at their correct angles at all times, and researching ways to reduce the quantum noise in interferometers.

I also have an interest in the application of precision interferometry techniques to other fundamental physics questions, like the measurement of birefringence of the vacuum, the search for new particles beyond the standard model, and more exotic questions.
