Research Bio
John Clarke is a Professor of the Graduate School in the Department of Physics. One of him main interests is in the development, noise limitations and applications of Superconducting Quantum Interference Devices (SQUIDs). He 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.
