I currently work in the Eöt-Wash group at the University of Washington’s Center for Experimental Nuclear Physics and Astrophysics (CENPA). Our group performs world-class measurements of gravity and tests of modern theories using torsion balances.
As an undergraduate at Brigham Young University, I worked in the high-intensity laser group led by Justin Peatross.
A motorized turntable in under 15 (times pi) minutes
I shared an office with a postdoc, Krishna, whose work centered around building an instrument to measure seismic tilt for LIGO, the gravity-wave observatory that made the first detection of gravitational waves. The instrument consisted of a long bar with weights on each end that hung from a pair of thin flexures EDM-cut from beryllium […]

Custom cleanroom for short-range gravity experiment
One of the main areas of investigation in our research group at UW is the behavior of gravity at short distances. We have tested Newton’s inverse-square law down to distances less than 100 microns, about the average width of a human hair. These tests involve objects with dimensions of a few inches, with surfaces that […]
