In this project we seek to advance understanding of how turbulent electromagnetic field topologies may scatter ions in the plasmas close to Sun. This process may drive heating and energization of the ion distributions through this region of space and forces plasma outward from the Sun in the Solar Wind...

Recent discoveries in near-Earth space have demonstrated a correlation between rapid changes in relativistic electron populations and the onset of intervals of electromagnetic turbulence during geomagnetic storms. Understanding the dynamics of these energetic particles remains an enigma despite decades of observations and theoretical modeling. Multiple processes have been identified...

Understanding turbulence in fluids and plasmas is one of the great challenges of physics. In Earth's near-space environment, known as the magnetosphere, turbulent fluctuations in electromagnetic fields and flows transport vast quantities of energy inward toward Earth through a channel of stretched magnetic field known as the magnetotail. This...

The spectacular display of light seen at high latitudes and known as the aurora is a consequence of the conversion of electromagnetic energy to particle kinetic energy. The motions in these luminous features are a marker for how the energy conversion operates. This project seeks to trace the motion of...
