PhD projects

Clive Speake’s main research interests are in experimental tests of gravitation. Within the Experimental Gravitational Physics group, which he founded, he has pioneered the use of superconducting suspensions for use as sensors of weak forces and also developed novel interferometers for use in cryogenic torsion balances. This has led to a patent on the design of an interferometer that is insensitive to mirror tilt-misalignment. These devices are now commercially available.

Professor Speake's research themes include:

Tests of the inverse square law of gravity
Measurement of Newton’s constant of gravitation
Development of superconducting levitation systems for detection of weak forces
Development of novel tilt-insensitive interferometers for commercial and research applications
