Caltech Experimental Gravity Group

What we work on

Our research spans five pillars that tie together gravitational-wave infrastructure, quantum measurement, foundational physics, advanced photonics, and AI for experimental control. These projects are developed in close connection with LIGO and collaborating laboratories.

• LIGO & Experimental Gravity Infrastructure — detector R&D, LIGO-India systems, coatings, and cryogenic optics.
• Quantum Measurement & Control — squeezed and non-Gaussian states, quantum-limited sensors, and robust feedback.
• Quantum Gravity & Foundational Physics — tabletop null tests, precision bounds, and reproducible protocols.
• Frontier Photonics & Energy Systems — high-power optics, coherent beam arrays, and pulsed laser fusion concepts.
• AI for Experimental Physics — data-driven control, diagnostics, and optimal design of complex experiments.

See the Research Pillars section for more detail on each area.
