John Clarke received his B.A. in 1964 and his M.A. and Ph.D. in 1968, all in Physics at the University of Cambridge, England. During 1968-69 he was a postdoctoral scholar at the Physics Department and Materials and Molecular Research Division of the Lawrence Berkeley Laboratory at the University of California, Berkeley. He has been a faculty member there since 1969.
His research has been mostly in solid state physics. He has developed several superconducting devices, including the dc Squid magnetometer. He has been involved with experiments on nonequilibrium superconductivity, and with experimental and theoretical work on 1/f noise. More recently, he has become interested in the application of Squid magnetometers to magnetotellurics, and in the analysis of magnetotelluric data.
