Dr Freise leads a small research team in the Gravitational Wave Group, working on new technologies and instrumentation for high-precision experiments.
Dr 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, and is currently chairing the simulation group of the GEO 600 collaboration. 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 142 peer-reviewed research papers (with an H-index of 46) 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: http://www.gwoptics.org.
