Prof. John Clarke

John Clarke received his B.A. (1964), Ph.D. (1968), and Sc.D. (2005) from Cambridge University. After a postdoctoral fellowship at UC Berkeley, he joined the Physics faculty in 1969.

Research focus

One of his main interests is in the development, noise limitations and applications of Superconducting Quantum Interference Devices (SQUIDs). Professor Clarke is particularly intrigued by quantum-limited detectors and measurements.  Applications include reading out superconducting “qubits”, novel schemes for ultra-low-frequency nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI), and searching for the axion.


Among other awards, in 2004 Professor Clarke received the Hughes Medal of the Royal Society in 2004. He was the UC Berkeley Faculty Research Lecturer in 2005.
