Short Description of your Research or Creative Project (700 characters or less)

Attempts to unify the Standard Model and General Relativity often include features that violate the Weak Equivalence Principle (WEP) and/or the gravitational Inverse-Square Law (ISL). To investigate this, researchers at Cal Poly Humboldt are conducting precision measurements of gravitational interactions below 50 microns. This project employs a torsion pendulum configured as a composition dipole with equal masses of titanium and aluminum. The twist angle and frequency of the pendulum is measured as an attractor mass in a parallel-plate configuration oscillates within submillimeter separations.
