David Reitze (born January 6, 1961 in Washington, Pennsylvania) is an American laser physicist who is Professor of Physics at the University of Florida and served as the scientific spokesman of the Laser Interferometer Gravitational-Wave Observatory (LIGO) experiment in 2007-2011. In August 2011, he took a leave of absence from the University of Florida to be the Executive Director of LIGO, stationed at the California Institute of Technology, Pasadena, California. He obtained his BA in 1983 from Northwestern University, his PhD in Physics from the University of Texas at Austin in 1990, and had positions at Bell Communications Research and Lawrence Livermore National Laboratory, before taking his faculty position at the University of Florida. He is a Fellow of the American Physical Society and the Optical Society of America.
An expert in ultrafast optics and laser spectroscopy, he now specialises in laser-based interferometric gravitational wave detection. This includes the development of new interferometer topologies for next generation gravitational wave detectors, investigations of thermal loading in passive and active optical elements, development of high power optical components, and the design, construction and operation of the LIGO interferometers.
In February 2016, he, as executive director of LIGO, announced that the first direct gravitational wave observation had occurred in September 14, 2015 by the LIGO Scientific Collaboration and Virgo Collaboration using the LIGO detectors in Hanford, WA and Livingston, LA.[a]
