Caltech Experimental Gravity Group
We design and operate precision experiments in gravitational physics, quantum measurement, and frontier photonics.
Research
Our work spans five pillars connecting gravitational-wave infrastructure, quantum measurement, foundational physics, advanced photonics, and AI for experimental control.
LIGO & Experimental Gravity Infrastructure
Build and upgrade the hardware and controls that make gravitational-wave interferometers work: lasers, optics, vacuum, suspension, and commissioning tools for current and next‑generation detectors.
Learn more →Quantum Measurement & Control
Develop quantum resources and measurement strategies—squeezing, non‑Gaussian states, and quantum links—to push precision sensing beyond standard quantum limits.
Learn more →Quantum Gravity & Foundational Physics
Design tabletop experiments that probe quantum aspects of gravity and test foundational questions at the interface of quantum mechanics and spacetime.
Learn more →Frontier Photonics & Energy Systems
Create high‑power photonic systems where coherence, damage thresholds, and feedback control are central challenges, with applications from advanced interferometers to energy‑relevant laser platforms.
Learn more →AI for Experimental Physics
Apply machine learning and control to complex experiments: faster lock acquisition, robust operation, automated diagnostics, and design optimization for precision instruments.
