Space Physicist
  • PhD, Physics
    2017, University of Texas at San Antonio
  • B.S., Physics
    2011, University of Texas at Arlington

My research interests lie in space plasma phenomena. This includes particle acceleration in the solar wind, interactions between the solar wind and planetary magnetospheres and surfaces, sources and evolution of magnetospheric plasma, wave-particle interactions, and space flight instrumentation. Experience includes comprehensive studies of plasma origin and subsequent evolution and acceleration in the magnetospheres of Venus, Earth, Jupiter, and Saturn, investigations on EMIC wave generation and propagation in the Earth’s outer magnetosphere, particle acceleration in the solar wind, as well as space flight instrumentation/calibration and space mission design. Responsibilities include serving as the Instrument Scientist for the Suprathermal Ion Spectrograph (SIS) sensor on Solar Orbiter, as a member of the Parker Solar Probe Project Science team, and as an Associate Editor for Frontiers in Astronomy and Space Sciences.
