Sam works on the GOES-R series magnetometers, which measure the Earth’s magnetic field at geostationary orbit.  The magnetometer is part of a suite of instruments designed to monitor space weather in order to alert customers of potential impacts ranging from power grid disruptions to hazardous energetic particle events in space.  Sam’s research interests include energetic particle dynamics in the Earth’s magnetosphere, electric and magnetic field measurements, spacecraft instrumentation, and instrument calibration.
