Broadband Measurement and Reduction of Quantum Radiation Pressure Noise in the Audio Band

Jonathan Cripe graduated from DePauw University with a B.A. and majored in physics and mathematics. After graduation, he studied for one year at the Albert Einstein Institute in Hannover, Germany, before starting his Ph.D. at Louisiana State University. While at LSU, Jonathan was a member of the LIGO collaboration and worked with Professor Thomas Corbitt on investigating quantum technologies for improving future generations of gravitational wave detectors. One of the highlights of his scientific career was participating in the first direct detection of gravitational waves. Jonathan is currently a physicist at the National Institute of Standards and Technology where he is applying his experience with radiation pressure to create reference devices for measuring nanonewton level forces.
