    • Brief Bio

    Ashley Greeley is a research scientist in the Energetic Particles Lab (code 672). She is the instrument lead on several cubesat missions analyzing electrons, protons, and ions in low Earth orbit (LEO), interplanetary space, and lunar orbit. She develops future missions using Geant4, a Monte Carlo simulation package. Her current research interests include electron pitch angle distributions in the Earth's radiation belts, wave-particle interactions, and particle precipitation into the atmosphere.
