About
Bio
Dr. Corey Jonathan Cochrane is a Research Scientist and Technologist in the Planetary Interiors and Geophysics group at NASA’s Jet Propulsion Laboratory (JPL). His research focuses on the measurement and interpretation of magnetic fields and plasmas in space to characterize planetary interiors and to assess their potential for harboring subsurface water.
Corey primarily works on NASA’s Europa Clipper mission as a Co-Investigator, Investigation Scientist, and Calibration Lead for the Europa Clipper Magnetometer (ECM); Co-Investigator and Investigation Scientist for the Plasma Instrument for Magnetic Sounding (PIMS); Co-Chair of the Interior Working Group (IWG); and Co-Chair of the JUICE/Clipper Steering Committee (JCSC). Outside of Europa Clipper, Corey’s strives to improve electromagnetic sounding techniques for detecting ocean worlds across the solar system, through the development of next-generation quantum magnetometers, novel ocean detection and characterization algorithms, and strategic design and formulation of future planetary mission concepts targeted for dynamic magnetic environments which provide powerful opportunities for exploration. He is the Principal Investigator of the optically pumped scalar–vector helium magnetometer (SVH) and the solid-state Silicon Carbide Magnetometer (SiCMag) currently being developed at JPL.
Corey obtained his Ph.D. in Engineering Science and Mechanics at Penn State, where he used magnetic resonance spectroscopy to study spin-dependent transport in quantum centers for magnetic field sensing. He also holds M.S. and B.S. degrees in Electrical Engineering from Penn State with emphases in signal processing and machine learning. Before joining JPL in 2013 as a NASA Postdoctoral Fellow, he spent two summers at NASA Ames developing biologically inspired robotics using neural networks and two years at Boeing Space & Intelligence Systems working in the DSP algorithms group.
