About

Bio

Dr. Corey Jonathan Cochrane is a scientist and technologist working in the Planetary Interiors and Geophysics group, with primary research interests in the measurement and study of planetary magnetic fields and plasmas. His research entails the search for ocean worlds in the solar system using electromagnetic sounding, through the development of next-generation quantum magnetometers, novel ocean detection and characterization algorithms, and strategic design and formulation of future planetary mission concepts.

Corey is an investigation scientist and the calibration lead for the Europa Clipper Magnetometer (ECM) investigation, an investigation scientist for the Plasma Instrument for Magnetic Sounding (PIMS) investigation, and the radiation focus group facilitator for NASA’s Europa Clipper mission. He was also a science affiliate with the Trident Discovery Mission concept developing algorithms for subsurface ocean detection at Triton on a single-pass using magnetometric measurements. He is the principal investigator of a next-generation Silicon Carbide Magnetometer (SiCMag) which leverages the electrical readout of quantum centers in SiC to sense magnetic fields. He is also a co-investigator of the Optically Pumped Solid-State Quantum Magnetometer (OPuS-MAGNM), the Gas And Ice Spectrometer Radar (GAISR) and Time-Resolved Raman spectrometer (TRRS) being developed at JPL. 

Corey obtained his PhD at Penn State in Engineering Science and Mechanics, where he used various forms of magnetic resonance spectroscopy as a means to characterize spin dependent transport of quantum centers in solid-state materials for use as magnetic field sensors. Corey also obtained his MS and BS degrees at Penn State in Electrical Engineering with emphasis in signal processing and artificial intelligence. He spent two summers at NASA’s Ames Research Center developing biologically inspired robotics using artificial neural networks and two years at Boeing Space & Intelligence Systems working in the DSP algorithms group. Corey came to JPL in 2013 where he was selected for a NASA Postdoctoral Program fellowship.
