Dr. Marshall's research encompasses physical phenomena in the near-Earth space environment, with common themes of naturally-occurring plasmas and interactions between charged particles and electromagnetic waves. He studies the radio emissions from lightning and uses them to study wave propagation in the ionosphere and magnetosphere. He studies radio wave interactions with meteor plasma through radar measurements and numerical modeling, in order to characterize the parent meteoroid. He studies the Earth's radiation belts, their interaction with waves in the magnetosphere, and the precipitation of these particles into the Earth's upper atmosphere, in order to characterize both the radiation belt populations and their effects on the atmosphere. Finally, Dr. Marshall builds a variety of instruments to make geophysical measurements, including sensitive radio, optical, and X-ray, and energetic electron instruments, for both ground-based and space-based experiments.
