Research Interests

Professor Evans' research is focused on gravitational wave detector instrument science, aimed at improving the sensitivity existing detectors and designing future detectors. In addition to his work on the Advanced LIGO detectors in Hanford, WA and Livingston, LA, in the labs at MIT Professor Evans explores the physical processes that set fundamental limits on the sensitivity of future gravitational wave detectors. Of particular interest are the quantum and thermal limitations which have the strongest impact on ground-based detectors like LIGO, and also play a role in the related fields of ultra-stable frequency references and macroscopic quantum measurement (MQM).

The Advanced LIGO detectors, which made the first direct detection of gravitational waves in September of 2015, operate by interleaving data taking with sensitivity improvements. The first major step beyond the Advanced LIGO design will come in 2017-2018 with the installation of a squeezed light source to reduced quantum noise in the readout (built by the LIGO group at MIT).

Biographical Sketch

Professor Evans received his B.S. in Physics from Harvey Mudd College in 1996 and his Ph.D. from California Institute of Technology in 2002. He continued his work on LIGO, the Laser Interferometer Gravitational-Wave Observatory, in his post-doctoral years at Caltech, then moved to the European Gravitational Observatory to work on the Virgo project. In 2007 he took a position at Massachusetts Institute of Technology as a research scientist working on the Advanced LIGO project, where he helped design and build the Advanced LIGO interferometer.

Prof. Evans moved to his current position at MIT in January 2013, at which point his research group began work on new technologies to improved Advanced LIGO sensitivity. In 2014 Prof. Evans was elected as chair-person of the Advanced Interferometer Configurations Working Group, where he is in charge of providing coherent design targets for future gravitational wave detectors. These design targets serve to give direction to instrument R&D in the LIGO Scientific Collaboration, and provide the foundation for the next generation of gravitational wave detectors.
