Gregory Harry Professor CAS | Physics

Degrees: PhD, physics, University of Maryland<br>MS, physics, University of Maryland<br>BS, physics, California Institute of Technology
Bio: Gregg Harry works to detect gravitational waves from supernovas, neutron stars, pulsars, and possibly the Big Bang. In this way, he is testing Einstein’s theory of gravity against Newton’s. An astrophysicist by trade, Harry works on the National Science Foundation–funded Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO). As part of the international collaboration, Harry’s central research has been to reduce thermal noise disruptions in the optics of the three, 4 km long interferometers that measure oscillations — warped space caused by gravitational waves — between mirrors at either end. At AU, Harry runs experimental labs for advanced physics students.
