Professor Freise leads a small research team in the Gravitational Wave Group, working on new technologies and instrumentation for high-precision experiments.

Professor Freise also has a leading role in the optical design of new gravitational wave detectors. For several years, he chaired the optical design working groups of the international projects Advanced Virgo and the Einstein Telescope. Furthermore, Freise has developed and maintains the software package Finesse, which is used world-wide for the design of interferometer systems.

Freise is a co-author on 168 peer-reviewed research papers (with an H-index of 63) in the field of gravitational wave research, and actively engaged in utilising new media for outreach and education. As such, Freise has recently created a dedicated web portal.


  • Dr. rer. nat. (Doctoral Studies in Physics) Universitaet Hannover 2003
  • Diplom Physik, Universitaet Hannover 1998
  • BSc Hons, Applied Physics with Microcomputing, Napier University 1995


Andreas Freise obtained his PhD in 2003 from the University of Hannover for developing new optical simulations and for significant contributions to the experimental realisation of the German-British gravitational wave detector GEO 600. He then became the first post-doctoral researcher at the newly established European Gravitational Observatory in Pisa to work on the Virgo detector, continuing his work to bring the first generation of gravitational wave detectors online. In 2005 Freise became a member of permanent academic staff in the School of Physics and Astronomy at the University of Birmingham, initiating a research activity on new technologies for high-precision experiments. The focus of his current research is on optics and interferometry for the Advanced LIGO project, the Einstein Telescope and future gravitational wave detector.

After having worked on both European detector sites, he actively supported the formation of a joint European community from the GEO and Virgo gravitational wave collaborations, which led to the successful FP7 design study for a future European research infrastructure, the Einstein Telescope.
